Backlight of Medium/Large-sized LCDs
BD9267KUT
●General Description
BD9267KUT is a white LED diver used on backlight of
Medium/Large-sized LCDs. This IC can achieve
dimming function by SPI control. And through the SPI
correspondence, it can set the ON/OFF of each switch,
analog dimming and etc. The signals of PWM dimming
can set the frequency, ON time and delay of PWM by
inputting the external signals to the register.

●Pin Function Descriptions
G1-G16 （1,4,7,10,13,16,19,22,27,30,33,36,39,42,45,48PIN）
External FET gate driving terminal of LED constant current driver, operating range : 0～5V.
S1-S16 （3,6,9,12,15,18,21,24,25,28,31,34,37,40,43,46PIN）
Connect to external FET’s source terminal of LED constant current driver。Through the operations of constant current
driver, all CHs of S1-S16 terminals are outputted the set voltages at addresses of 02h, 03h, and S1-S16 proceed the
constant current operation.
By monitoring the voltage of this terminal, the external resistance SHORT detection of each CH and external MOS
SHORT during Drain-Source detection proceed.
When Dimming＝HIGH, external resistance SHORT detection proceeds, and output the errors.
When Dimming＝LOW, external MOS Drain-Source SHORT detection proceeds, and output the errors.
D1-D16 （2,5,8,11,14,17,20,23,26,29,32,35,38,41,44,47PIN）
At output terminal of LED constant current driver, drain of external FET is connected. By monitoring the voltage of this
terminal, LED OPEN detection and LED SHORT detection of each terminal proceed.
When Dimming＝HIGH, if LED is in SHORT mode or OPEN mode, error signals are outputted.
LED OPEN protection detected voltage ・・・0.1V(typ.)
LED SHORT protection detected voltage・・・5.0V(typ.)・・・(It can be changed by setting the LSP terminal. Details are
given in LSP Pin Description.)
When Dimming ＝ LOW, the abnormal state when Dimming ＝ HIGH just before continues. In other words, when
Dimming=HIGH and the abnormal state is detected, the error signal is still outputted even turned to Dimming＝LOW.
To prevent the mistake of detection caused by the time change of state, abnormal detection mask can be set at address
of 04h.
At D1～16 pin
① LED OPEN detection（when PWM=H）
② LED SHORT detection（when PWM=H）
At S1～16 pin
③ RESISTOR SHORT detection（when PWM=H）
④ MOS SHORT detection（when PWM=L）
are detected, then the error signals are outputted.
Figure 10. LED Protected operation
VREF5V （49PIN）
The VREF5V pin is used to output power (5V) to the internal block of the IC and serves as a main power supply for the
internal circuit of the IC. Install a ceramic capacitor as close to this pin as possible in order to stabilize the power supply
voltage.

LSP （50PIN）
A pin used for setting the LED SHORT protection detecting
voltage. When LSP pin is in OPEN state, the voltage in inward
of IC is 1V typ.（Set it in range of 0.8V~3.0V）
When LED is lighting, if the voltage of D1～16 pin is higher
than
「Voltage of LSP x 5 (V) 」
（default 5V）
the abnormal state of IC is detected。
Because this pin has a high impedance, please connect a
capacitor about 1000pF to remove the noise basically.

VCC （51PIN）
The VCC pin is used to supply power for the IC in the range of 9 to 35V. If the VCC pin voltage reaches 7.0V (Typ.) or
more, the IC will initiate operation. If it reaches 6.7V (Typ.) or less, the IC will be shut down. Basically, insert a resistor of
approx. 10 ohms in resistance between the VCC pin and the external power supply and install a ceramic capacitor of
approx. 1uF in capacitance in the vicinity of the IC.
STB （52PIN）
The STB pin is used to make setting of turning ON and OFF the IC and allowed for use to reset the IC from shutdown.
Note: Set the STB pin voltage below the VCC pin voltage.
Note: The IC state is switched (i.e., the IC is switched between ON and OFF state) according to voltages input in the STB
pin. Avoid using the STB pin between two states (0.8 to 1.8V).
GND（53PIN）
The GND pin is an analog circuit ground pin of the IC. Set the ground pattern as close as possible to that of resistors
connected to the S1 to S16 pins.
COMP1(55PIN)
The COMP1 pin is used to feed back the state of voltage to the external power supply in order to optimize the power
supply voltage for the LED layer.
Positive feedback voltage is output to a pin having the lowest voltage out of the D1 to D8 pins. If the lowest voltage of the
D1 to D8 pins is higher than 0.6V typical voltage, the COMP1 pin will become open-circuited. If the lowest voltage of
these pins is lower than 0.6V typical voltage, the internal NPN transistor of the COMP1 pin will turn ON. The COMP1 pin
is intended to connect to the output voltage monitor pin of the DC/DC converter.

COMP2(54PIN)
The COMP2 pin is used to feed back the state of voltage to the external power supply in order to optimize the power
supply voltage for the LED layer.
Positive feedback voltage is output to a pin having the lowest voltage out of the D9 to D16 pins. If the lowest voltage of
the D9 to D16 pins is higher than 0.6V typical voltage, the COMP2 pin will become open-circuited. If the lowest voltage of
these pins is lower than 0.6V typical voltage, the internal NPN transistor of the COMP2 pin will turn ON. The COMP2 pin
is intended to connect to the output voltage monitor pin of the DC/DC converter.
CS(57PIN), CLK(58PIN,) DI(59PIN), DO(60PIN)
These pins are used to control the IC with the CS, CLK, DI, and DO serial interfaces. Input levels are determined by the
DVDD power supply of the digital block. For data input format and timing, refer to the description of Logic block to be
hereinafter provided.
Input State
Input Level
High-level input
DVDD×0.7~ DVDD+0.3[V]
Low-level input
-0.3~DVDD×0.3 [V]
VSYNC(61PIN), HSYNC(62PIN)
The VSYNC and HSYNC input signals enable the PWM light modulation signal to make setting of PWM frequency, PWM
ON time, and PWM delay time. For data input format and timing, refer to the description of Logic block to be hereinafter
provided.
ERR_DET(63PIN)
The ERR_DET pin is used to output an IC error detection signal and provides the N-MOS open-drain output function. If
this pin is pulled up to the DVDD voltage of the IC or else, it will be set to output High voltage for normal operation. If any
error is detected, the internal NMOS of the IC will be put into ON state, setting the pin to output Low voltage.

LED error detection
GND Level
When the ERR_DET pin is put into the GND Level, the LED has already caused an error. In this case, reading the
registers located at addresses 05h to 0Ch makes it possible to recognize what channel is in what type of error state. (For
detail, refer to the description of registers to be hereinafter provided.)
DGND(56PIN)
The DGND pin is a digital circuit ground pin of the IC. Lay out the DGND pin using interconnect independent of that for
the GND pin wherever possible.
DVDD(64PIN)
The DVDD pin is used to input power in the digital block of the IC in the range of 3.0 to 3.6V. When the DVDD pin voltage
reaches 3.3V (typ.), the IC will start operating. Insert a ceramic capacitor of approx. 1uF in capacitance between the DVDD
and DGND pins in the vicinity of the IC.

Figure 17. Setting for PWM Delay and ON Duty
By making register setting, PWM output delay and ON duty time counts of CH1 to CH16 can be controlled.
The above timing chart shows an example for CH1.
(To make delay time count setting, write 06h in address 2Ch. To make ON duty time count setting, write 07h in address 0Ch.)
The delay counter starts counting after counting three from the leading edge of VSYNC signal. When the counter reaches the
set delay count value (06h), the duty counter will start counting simultaneously when the PWM_OUT_01 signal is set to “H”.
Subsequently, when the duty counter reaches the set duty count value (07h), the PWM_OUT_01 signal will be set to ”L”.
Since then, the said sequence is continuously repeated.
The same control is also carried out for CH2 to CH16.
The delay counter counts up to FFCh. Even if the set value exceeds this maximum value, it will also count up to FFCh.
●oft-start masking function
A value set at address 09h serves as the pulse number of the VSYNC signal and masks the error signal control in the
relevant section.

[Operation］
The pwm_mskcnt counter starts counting from the falling edge of HSYNC4I next to the signal that set LED_OP_01 to
“H”. When the counter reaches the set count (02h), the err_maskcnt counter will start counting. When the counter
reaches the set count (02h), the ERROR output signal will be set to “H”.
Subsequently, the error state is continually monitored at the leading edge of pwm_out_01 and judged as “Error not
detected”. After that, when the pwm_mskcnt counter reaches the set count value, the ERROR output signal will be
set to “L”.
The count numbers of pwm_mskcnt and err_mskcnt for the detection signal (4) are the same as those for the
detection signals (1) to (3).

●Precautions in use
1.) This product is produced with strict quality control, but might be destroyed if used beyond its absolute maximum ratings including
the range of applied voltage or operation temperature. Failure status such as short-circuit mode or open mode can not be
estimated. If a special mode beyond the absolute maximum ratings is estimated, physical safety countermeasures like fuse
needs to be provided.
2.) The circuit functionality is guaranteed within of ambient temperature operation range as long as it is within recommended
operating range. The standard electrical characteristic values cannot be guaranteed at other voltages in the operating ranges,
however the variation will be small.
3.) When this product is installed on a printed circuit board, attention needs to be paid to the orientation and position of IC. Wrong
installation may cause damage to IC. Short circuit caused by problems like foreign particles entering between outputs or
between an output and power GND also may cause damage.
4.) The pin connected a connector need to connect to the resistor for electrical surge destruction.
5.) Use in a strong magnetic field may cause malfunction.
6.) Thermal design needs to be done with adequate margin in consideration of allowable loss (Pd) in actual operation state.
7.) This IC includes temperature protection circuit (TSD circuit). Temperature protection circuit (TSD circuit) strictly aims blockage of
IC from thermal runaway, not protection or assurance of IC. Therefore use assuming continuous use and operation after this
circuit is worked needs to not be done.
8.) This IC is a monolithic IC which has P+ isolation for separation of elements and P board between elements.
A P-N junction is formed in this P layer and N layer of elements, composing various parasitic elements.
For example, a resistance and transistor are connected to a terminal as shown in the figure,
○
When GND>(Terminal A) in the resistance and when GND>(Terminal B) in the transistor (NPN), P-N junction operates
as a parasitic diode.
○
When GND>(Terminal B) in the transistor (NPN), parasitic NPN transistor operates in N layer of other elements nearby
the parasitic diode described before.
Parasitic elements are formed by the relation of potential inevitably in the structure of IC. Operation of parasitic elements can
cause mutual interference among circuits, malfunction as well as damage. Therefore such use as will cause operation of
parasitic elements like application of voltage on the input terminal lower than GND (P board) need to not be done.
