●Description
BD6086GU is a composite LED driver best-suited for mobile phone display.
With an analog illumination intensity sensor connected, this LED driver mounts an auto luminous control (ALC) function
capable of automatically adjusting the backlight current depending on an ambient illumination intensity to reduce the set
power consumption. With a key backlight driver mounted, this driver enables the ON/OFF setting to be made depending on
the ambient illumination intensity. In addition, this driver realizes an eye-catching display through the use of two RGB LED
drivers supporting a slope control function.
With two channels of variable output type regulators mounted, this driver can be used for LCD and camera. This driver
eliminates the need for additional wirings on a flexible substrate through the GPIO mounted.
2
The DC/DC module adopts a charge pump system and rarely uses a coil. Furthermore, it employs a VCSP85H4 (4.5mm
0.5mm pitch) chip size package for compaction and thinness.
●Futures
1) LED Driver (7ch) for LCD Backlight
・Incorporates 4 channels for main settings and 3 channels optionally selectable for either independent control or main
setting depending on register settings.
・Provides a driver assigned for main settings with various functions such as an automatic current value adjustment
function by an illumination intensity sensor, a slope control function against current value variation, an LED current
value adjustment function for reflecting a setting value in a register through external pin synchronization and an LED
current value adjustment function through external pin PWM input.
2) RGB LED driver (dual driver)
・Incorporates a slope control function (capable of controlling dual drivers independently)
・Capable of selecting (setting) a battery or DC/DC output module as a destination (register setting)
・Capable of using one driver for GOP output mode (register setting)
3) Illumination intensity sensor interface
・Incorporates various functions such as a sensor bias adjustment function, an ADC with an average filter, a gain/offset
adjustment function and an LOG conversion function so that options can be increased for illumination intensity
sensors (Photo Diode, Photo Transistor, Photo IC (Linear/LOG)).
・Incorporates an auto gain switching function for suppressing an illumination intensity sensor current at high
illumination intensity and improving sensitivity at low illumination intensity
・Capable of customizing an LED current value according to a table setting.
4) Built-in regulator (2 channels)
・REG1 2.8V Iomax=150mA
Low power consumption mode available
・REG2 1.5V/1.8V Iomax=150mA
Low power consumption mode available
・REG1, REG2
Both can be controlled independently via external pins.
5) Charge pump system DC/DC
・Supports an output voltage fixed mode function (3.9V/4.2V/4.5V/4.8V)
・Mounts a soft start function, an overvoltage protection function (auto recovery type) and an overcurrent protection (auto recovery)
6) Key backlight controller
・Capable of ON/OFF control depending on an ambient illumination intensity
・Capable of adjusting key backlight brightness via MAX DUTY setting
・Capable of making an fade-in/fade-out setting via PWM

・Bit Transfer
SCL transfers 1-bit data during H. SCL cannot change signal of SDA during H at the time of bit transfer. If SDA changes
while SCL is H, START conditions or STOP conditions will occur and it will be interpreted as a control signal.
SDA
SCL
SDA a state of stability：
SDA
It can change
Data are effective
・START and STOP condition
When SDA and SCL are H, data is not transferred on the I2C- bus. This condition indicates, if SDA changes from H to L
while SCL has been H, it will become START (S) conditions, and an access start, if SDA changes from L to H while SCL
has been H, it will become STOP (P) conditions and an access end.

・Acknowledge
It transfers data 8 bits each after the occurrence of START condition. A transmitter opens SDA after transfer 8bits data, and
a receiver returns the acknowledge signal by setting SDA to L.

・Writing protocol
A register address is transferred by the next 1 byte that transferred the slave address and the write-in command. The 3rd
byte writes data in the internal register written in by the 2nd byte, and after 4th byte or, the increment of register address is
carried out automatically. However, when a register address turns into the last address, it is set to 00h by the next
transmission. After the transmission end, the increment of the address is carried out.

・Reading protocol
It reads from the next byte after writing a slave address and R/W bit. The register to read considers as the following address
accessed at the end, and the data of the address that carried out the increment is read after it. If an address turns into the
last address, the next byte will read out 00h. After the transmission end, the increment of the address is carried out.

・Multiple reading protocols
After specifying an internal address, it reads by repeated START condition and changing the data transfer direction. The
data of the address that carried out the increment is read after it. If an address turns into the last address, the next byte will
read out 00h. After the transmission end, the increment of the address is carried out.

As for reading protocol and multiple reading protocols, please do A(not acknowledge) after doing the final reading
operation. It stops with read when ending by A(acknowledge), and SDA stops in the state of Low when the reading
data of that time is 0. However, this state returns usually when SCL is moved, data is read, and A(not acknowledge)
is done.

●Description of white LED Driver Operations
・ Comprises four lights (WLEDs1-4) for the main driver and three lights (WLEDs5-7) for general-purpose drivers.
・ Permits the main driver to select either a fixed current mode based on a register or an auto light control mode by the
auto light control module.
・ Enables a general-purpose driver to designate an independent control mode based on a register and its attribution to
the main group in units of terminals. This function makes it possible to assign the drivers easily depending on set
designs such as main 4 LEDs/sub 2 LEDs/indicator 1ch and main 6 LEDs/sub 1 LED.
・ Implements control as shown below when main group setting is designated via the W*MD bit.
Current setting:
Operates in conjunction with IMLED(6:0) (IW*(6:0) is discarded.)
ON/OFF control:
Operates in conjunction with MLEDEN. (W*EN is discarded.)
・ Enables the main group to control PWM via the external terminal so that brightness control can be accomplished from
the outside.
PWM control:
Inputs PWM via the external terminal “WPWMIN.”
External synchronization:
Corrects a current value set by IOFS (5:0) in synchronization with the
external terminal “OSYNC.”
・ Determines the LED current via a built-in resistance.
Permits the main group to perform slope processing so that the leading/trailing edge time can be set individually. The
settings made in the registers THL (3:0) and TLH (3:0) are effective regardless of their light control mode (ON/OFF). To
enable instant activation, the minimum value must be set for time.
●RGB LED Driver Operation Description
・ Two drivers “RGB1 (R1LED, G1LED, B1LED)” and “RGB2 (R2LED, G2LED, B2LED)” are mounted.
・ A slope function is incorporated to control drivers independently.
・ Refer to  RGB Waveform Setting for more information about output waveform setting.
・ RGB2 can be used for GPO (Open drain output) It can be set up in every terminal with the register R2GPO, G2GPO
and B2GPO.
・ The LED current can be set via a resistance value (RISET) to be connected to the RGBISET terminal.
The maximum current value can be derived from the following expression:
ILEDmax [A] = 3.048 / RISET [kΩ] (Typ)
However, this setting must be made so that the maximum current value can be less than or equal to 30.48mA. In
addition, the RGBISET terminal has an overcurrent protection circuit to prevent the excessive LED current from flowing
for low impedance to the ground.
・ Connection of each LED of RGB can be set up in VBAT or VOUT by the register RGB1PW (1:0) and RGB2PW (1:0).
When Vf is low, it is connected to VBAT, and it is possible that efficiency is raised. When a VBAT connection is chosen,
a return route to the DC/DC circuit is interrupted, and it works as a simple constant current driver. In this case, set it up
to be less low than the saturation voltage (0.2V) of the fixed electric current circuit.

●General-purpose I/O Ports (GPIO1-GPIO4)
Capable of selecting GPI and GPO independently according to the register setting.
Capable of selecting a complementary or open drain output method so long as GPO is selected.
Uses a VGPIO applied voltage as a logic level (during CMOS output setting and input setting).
When open drain output is selected, a pull-up resistance may be connected to a desirable location (VPUP) but the
condition of VGPIO≧VPUP must be satisfied.
・ Capable of outputting an interrupt signal via the INTB terminal (NMOS open drain) depending on an input logic change
2
in each terminal and reading an input logic and an interrupt factor via I C so long as GPI is selected.
Reflecting interrupts can be selected individually.
When input mask is set:
An input logic is sampled at the leading edge of a clock (having a frequency obtained by dividing 32KIN by 256).
When a sampling value differs from the contents of the existing output register consecutively three times, it is
reflected on the output register (input logic and interrupt factor).
No input logic change is reflected on the INTB output.
When input mask is reset:
An input logic is sampled at the leading edge of a clock (having a frequency obtained by dividing 32KIN by 256).
When a sampling value differs from the contents of the existing output register consecutively three times, it is
reflected on the output register (input logic and interrupt factor).
In addition, an interrupt pulse (one cycle of 32KIN with negative logic) is output simultaneously via INTB. The
interrupt factor can be cleared by setting GPCLR (Address=23h, Bit=7) to H.
・ Provide an idle GPIO terminal with a resistance of about 100kΩ for pull-down. (When GPIO1 to GPIO4 and KBLT are
not used at all, short-circuiting of VGPIO and GND eliminates the need for using this pull-down resistance.)
・ Each terminal of the GPIO block is initially set as follows:
GPIOs1-4:
I/O mode
When using the output mode: The breakthrough current flows on an input buffer circuit until the
output mode is set. When there is a problem, be sure to connect a pull-down resistance.
Once the output mode is set, the input buffer circuit must be set to OFF so that the breakthrough
current cannot flow.
When using the input mode: The breakthrough current flows on an input buffer circuit unless an
input voltage is fixed. When there is a problem, be sure to connect a pull-down resistance to fix
the input voltage.
KBLT:
L (A pull-down resistance is incorporated to prevent unstable output at voltage supply.)
INTB:
Employs an external pull-down to set “H” for open drain output.

・
Apply voltage to VGPIO as follows to prevent a malfunction which causes an unexpected operation on a GPIO circuit
at activation time. VIO and VGIO may be short-circuited. Even when only GPIO is used, voltage should apply to VIO
too. To avoid erroneous output to the INTB terminal at activation time, don’t reset the input mask of GPIO* prior to an
elapse of 30ms after 32KN input. Because internal IO is activated at clock input, current dissipation arises even in the
standby state. When there is a problem, stop 32KIN input.

●Key Backlight Controller
・ Capable of turning ON or OFF the key backlight according to the register setting or via the automatic light control
module.
・ Capable of adjusting illumination (ON time) according to the Duty setting via the built-in PWM (PWM frequency:
488Hz) and fade-in/fade-out via the slope function which steps PWM Duty at time intervals set in the KBSLP register.
・ Determines a key backlight PWM frequency based on an internal clock rate of 1MHz. This value is identical to that at
Typ (1MHx).
・ Enables the selection of complementary or open drain for output and allows diversion to GPO.
・ Uses a VGPIO applied voltage as a logic level (during CMOS output setting and input setting).
When open drain output is selected, a pull-up resistance may be a desirable location (VPUP) but the condition of
VGPIO≧VPUP must be satisfied.
・ Mandatory to supply voltage to VGPIO for key backlight controller operations.
For a key backlight controller operating in conjunction with an auto luminous control (ALC) module
The register “KBFIX” must be set to 0 to enter the auto luminous control mode.
The ON/OFF condition to illumination intensity is set in the registers CTH (3:0) and CHYS (1:0).
The ON/OFF patterns of the key backlight are set in the registers MDTY (3:0) and KBSLP (1:0).
(For details of auto luminous control module setting, refer to ●Description of Auto Luminous Control Module
Operations.)
For a key backlight controller capable of ON/OFF control according to register settings
The register “KBFIX” must be set to 1 to enter the register setting mode.
The slope time is set in the register “KBSLP (1:0).”
When the key backlight is turned ON, data equivalent to illumination intensity must be set in MDTY (3.0). When
it is turned OFF, “0h" must be set instead.
For a key backlight controller to be used as GPO
The register “KBFIX” must be set to 1 to enter the register setting mode.
The register "KBSLP (1:0)” is set to 00 (without slope).
When “H” level output takes place as a GPO, the register “MDTY (3:0)”must be set to Fh. In contrast, when "L"
level output takes place, the MDTY (3.0) must be set to 0h instead.

●RGB Waveform Setting
Various kinds of RGB control can be implemented by designating waveform cycles, waveform patterns, current settings 1, 2
and rising/falling slope times.
To activate a RGB waveform, a continuous operation via RGB*EN or a single-shot operation via RGB*OS can be selected.
In addition, when control via the external terminal RGB*CNT is enabled via RGB*MEL, the corresponding LED can be lit in
synchronization with the external signal.
1. Waveform cycle
・ingle cycle time is set for a waveform pattern.
・This setting can be made independently for RGB1 and RGB2.
2. Waveform pattern
・A pattern in a waveform cycle is set.
・Sixteen types of waveform patterns can be set in units of waveform patterns.
・For concrete waveform patterns, refer to the timing diagram shown on the next page.
3. Current settings 1 and 2 (I1, I2)
・Two currents in a waveform pattern are set.
・When the maximum current value is 25.4mA, it is possible to set the current ranging from 0 to 25.4mA with an increment
of 0.2mA (128 steps).
・The polarity of a waveform is determined by the greater-than/ less-than relationship in the current setting.
・This setting can be made in units of terminals.
4. Rising/falling slope time
・A current change time during switching between current settings 1 and 2 is set.
A time per step (0.2mA) is calculated based on a difference between the currents selected in current settings 1, 2 and a
setting slope time.
For this reason, a time per step (0.2mA) is short when a difference between setting currents I1 and I2 is large. In
contrast, it is long when a difference between setting currents I1 and I2 is small.
・Regardless of current settings 1 and 2, a rising slope time applies at current increase and a falling slope time applies at
current decrease. For concrete waveform images, refer to the timing diagram shown on the next page.
5. External terminal synchronization control
When control via the external terminal RGB*CNT is enabled via RGB*MEL, lighting is enabled if the input external signal
goes “H.” In contrast, it is disabled if the external input signal goes “L.” In this way, synchronization with the external
signal is enabled so that LED can be blinked in conjunction with a ringing tone (a melody signaling a ringtone).

6. Clock external output
The clock (31.25kHz (TYP)) of this LSI is output by making the setup of the register GPO1OSC "1" from the GPIO1
terminal. (Internal OSC is turned on separately, and you must make GPIO1 a setup of output.)
As extension of illuminations, a clock can be supplied to other RGB LED drivers, and it can be made to synchronize with
this LSI. It is applicable to a clock supply means in case there is no clock for GPIO (32KIN).

●Description of DC/DC Operations
Activation
The DC/DC circuit is activated when any LED is subject to lighting control (DCDCFON=0).
(However, this is true only when the output (VOUT) of the DC/DC circuit is set as a LED connection destination.) A soft
start function is available to prevent the rush current at DC/DC circuit activation.
Note that voltage should apply to both VBAT and VIO as follows:
DCDCMD=1 must be set in the fixed voltage mode and DCDCMD=DCDCFON

But, as for Ta > TTSD (typ : 195° C), a protection function functions, and an EN signal doesn't become effective.
TSOFT changes by the capacitor connected to VOUT and inside OSC.
TSOFT is Typ 200μs (when the output capacitor of VOUT =1.0μF).
Overvoltage protection/Overcurrent protection
The DC/DC circuit output (VOUT) is provided with an overvoltage protection function and an overcurrent protection function.
VOUT overvoltage detection voltage: approx. 6.0V (during a VOUT voltage rise)
A detection voltage has a hysteresis and its detection cancel voltage is approx. 5.75V (reference design value). In addition,
when the VOUT output is short-circuited to GND, the leak current is suppressed via the overcurrent protection function.

●Description of other operations
1.Reset
There are two types of reset: software reset and hardware reset.
(1) Software reset
・Setting the register (SFTRST) to “1” causes all the registers to be initialized.
・The registers subject to software reset automatically return to zero (Auto Return 0).
(2) Hardware reset
・Changing the RESETB terminal setting from “H” to “L” causes a state subject to hardware reset.
・Attempting hardware reset causes the states of all registers and output terminals to be initialized to their initial values,
so that address reception is entirely stopped.
・Attempting reset in the hardware reset state causes the RESETB terminal state to change from “L” to “H” and vice
versa.
・The RESETB terminal is provided with a filter circuit and a duration of 5µs or less with the terminal set to “L” is not
recognized as hardware reset.
(3) Reset sequence
・When hardware reset is attempted during software reset, software reset is already cleared when hardware reset is
cleared (because the software reset initial value is 0).
2.Thermal shutdown
A thermal shutdown function is effective in the following block.
DC/DC (Charge pump)
LED driver
REG1,2 (Normal mode)
SBIAS
The thermal shutdown function is activated when the detected temperature is approx. 195C.
The detected temperature has a hysteresis and the detection cancel temperature is approx. 175C (reference value in
design).
3. I/O portion
While the RESETB terminal is in “L” state, no input signal is propagated to the IC logic portion because SDA and SCL
input buffer operations are all stopped.
When RESETB=L, output is fixed at “H.”

Special care should be taken because a current path may be formed via a terminal protection diode, depending on an

Technical Note
●Notes for use
(1) Absolute Maximum Ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc.,
can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If
any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical
safety measures including the use of fuses, etc.
(2) Power supply and ground line
Design PCB pattern to provide low impedance for the wiring between the power supply and the ground lines. Pay
attention to the interference by common impedance of layout pattern when there are plural power supplies and ground
lines. Especially, when there are ground pattern for small signal and ground pattern for large current included the
external circuits, please separate each ground pattern. Furthermore, for all power supply pins to ICs, mount a capacitor
between the power supply and the ground pin. At the same time, in order to use a capacitor, thoroughly check to be sure
the characteristics of the capacitor to be used present no problem including the occurrence of capacity dropout at a low
temperature, thus determining the constant.
(3) Ground voltage
Make setting of the potential of the ground pin so that it will be maintained at the minimum in any operating state.
Furthermore, check to be sure no pins are at a potential lower than the ground voltage including an actual electric
transient.
(4) Short circuit between pins and erroneous mounting
In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting
can break down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between pins or between
the pin and the power supply or the ground pin, the ICs can break down.
(5) Operation in strong electromagnetic field
Be noted that using ICs in the strong electromagnetic field can malfunction them.
(6) Input pins
In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the
parasitic element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of
the input pin. Therefore, pay thorough attention not to handle the input pins, such as to apply to the input pins a voltage
lower than the ground respectively, so that any parasitic element will operate. Furthermore, do not apply a voltage to the
input pins when no power supply voltage is applied to the IC. In addition, even if the power supply voltage is applied,
apply to the input pins a voltage lower than the power supply voltage or within the guaranteed value of electrical
characteristics.
(7) External capacitor
In order to use a ceramic capacitor as the external capacitor, determine the constant with consideration given to a
degradation in the nominal capacitance due to DC bias and changes in the capacitance due to temperature, etc.
(8) Thermal shutdown circuit (TSD)
This LSI builds in a thermal shutdown (TSD) circuit. When junction temperatures become detection temperature or
higher, the thermal shutdown circuit operates and turns a switch OFF. The thermal shutdown circuit, which is aimed at
isolating the LSI from thermal runaway as much as possible, is not aimed at the protection or guarantee of the LSI.
Therefore, do not continuously use the LSI with this circuit operating or use the LSI assuming its operation.
(9) Thermal design
Perform thermal design in which there are adequate margins by taking into account the permissible dissipation (Pd) in
actual states of use.
(10) LDO
Use each output of LDO by the independence. Don’t use under the condition that each output is short-circuited because
it has the possibility that an operation becomes unstable.
(11) About the pin for the test, the un-use pin
Prevent a problem from being in the pin for the test and the un-use pin under the state of actual use. Please refer to a
function manual and an application notebook. And, as for the pin that doesn't specially have an explanation, ask our
company person in charge.
(12) Rush Current
Rush current may flow in instant in the internal logic unfixed state by the power supply injection order and delay.
Therefore, be careful of power supply coupling capacity, a power supply and the width of grand pattern wiring, and
leading about.
(13) About the function description or application note or more.
The function manual and the application notebook are the design materials to design a set. So, the contents of the
materials aren't always guaranteed. Please design application by having fully examination and evaluation include the
external elements.
