MLP-16 [4x4] Package
1.33MHz and 250kHz Programmable Fixed Frequency
Separate Brightness Zones for Multiple Displays
Three Charge Pump Modes of Operation: 1x, 1.5x and 2x
Open LED Output Protection
LED outputs are current-matched for consistent LED brightness.
Up to 6 LEDs are controlled in three zones for brightness control in
multiple displays. The 6 LED outputs are divided into 3 pairs of
LEDs. Each pair has current that is programmable independent of
the other pairs. Any combination of LEDs may be turned on using
the serial interface. The SC606 also has a float detect feature
that disables any current driver during normal operation when an
open-load condition is detected.
Patented low noise switching circuitry and constant output current
allow the use of extremely small input and output capacitors.

Applications Information
VTRANS1X = VF + VILEDn +(# of LEDs used) ILED 0.83
Detailed Description
VTRANS1.5X = [VF + VILEDn +(# of LEDs used) ILED 10.1]/1.5
The SC606 contains a fractional charge pump, mode selection
circuit, serial I/O logic, serial data registers and current regulation
circuitry for 6 LED outputs. All are depicted in the Block Diagram
on page 6.
where, VF is the anode to cathode voltage and VILEDn is the voltage
at the ILED pin. Typically VILED=120mV and ILED is the LED current.
Power efficiency can be estimated for the intended battery voltage
range.
The fractional charge pump multiplies the input voltage by 1, 1.5
or 2 times the input voltage. The charge pump switches at a fixed
frequency that is bit selectable to 1.33MHz or 250kHz. The default
frequency is 1.33MHz. 250kHz may require additional input
capacitance of up to 10μF. The charge pump does not switch
during 1x mode, saving power and improving efficiency.
η = [VOUT IOUT / VIN (IOUT Mode+IQ)] 100 %
where, VOUT = VF+ VILEDn
and
IQ = 1.5mA, in 1x mode
IQ = 3mA, in 1.5x or 2x mode
The mode selection circuit automatically selects the mode as 1x,
1.5x or 2x based on circuit conditions such as LED voltage, input
voltage and load current. 1x is the most efficient mode, followed
by 1.5x and 2x modes. At lower voltages a stronger mode may be
needed to maintain regulation. If so , the mode will change first to
1.5x and then later to 2x. 2x mode usually operates for a much
shorter run time compared to 1x mode, and 2x mode maintains
the output until the battery is discharged to 2.85V or less. The LED
requiring the highest voltage drop will determine the output voltage
needed to drive all outputs with sufficient anode voltage.
Comparing all cathodes and regulating VOUT for the LED with the
lowest cathode voltage ensures sufficient bias for all LEDs.
Quiescent Current
IQ at no load will vary with the device state. A sequence of steps is
now described which will demonstrate the effect that the device
state has on IQ when VIN = 3.8V.
(1) After power up (Enable High) and before any serial
communication, the IQ is approximately 2.2mA. This is because
the output defaults to 5V and the charge pump is active to support
the 5V. The charge pump also defaults to 1.33MHz.
(2) After power up if the clock is changed to 250kHz, the IQ will
decrease to 1mA.
The LED outputs are controlled through the serial data registers,
found on page 10 in Table 1. LED on/off functions are
independently controlled, so that any combination of LEDs may be
switched on. LED current is set per LED pair. For example, when
ILEDA1 and ILEDA2 are both on, ILEDA1 = ILEDA2. But ILEDA1 and
ILEDA2 do not have to be on at the same time.
(3) If one LED is set on at 0.5mA, the input current will be 1.5mA.
For a typical white LED, the 5V output is much higher than
necessary, so the charge pump will switch off and the output will
adjust to a normal value for the LED, typically around 3.5V.
(4) Turn off the LED and IQ = IIN = 80μA with Enable = High. This is
the lowest power state while Enable = High.
Six (6) current regulating circuits sink matched currents from the
LEDs on a per pair basis. LEDs with matched forward voltage will
produce the best possible matched currents. For best matching
performance it is recommended that the LED to LED difference,
ΔVF , be under 250mV.
ILED Accuracy
ILED is determined by the status of registers at 00h, 01h and 02h.
The tolerance of the ILED current is +/-6.5% at the 10mA setting.
For example, if the data registers are configured so that each LED
current should be 10mA, the actual LED currents would be between
9.35mA and 10.65mA (+/-6.5%). All 6 outputs meet this
requirement over the industrial temperature range. To calculate
the error ILED-ERR[%], use the formula,
Designing for Lowest Possible Battery Current
The battery current and efficiency of the SC606 are mostly
dependent on the charge pump mode of operation. To get the
best performance from the SC606 it is better to use LEDs with
consistantly lower VF voltage. Lower VF will keep the charge pump
in 1x mode longer and will use less battery current, extending the
run time of the battery.
ILED-ERR[%] = ±
Mode transition voltages VTRANS1X and VTRANS1.5X can be estimated
by the following equations:

1x Mode, 1.5x Mode and 2x Mode
1x Mode, 1.5x Mode and 2x Mode all refer to the charge pump
configuration. These modes multiply the input voltage and ensure
that VOUT is high enough for current to be regulated in the LEDs.
Mode Transition Voltage
Mode transition voltage refers to the input voltage at the point
when the charge pump changes from a weaker mode (lower
numerically) to a stronger mode (higher numerically). VTRANS1X is
the transition from 1x to 1.5x mode, and VTRANS1.5X is the
transition from 1.5x to 2x mode.

I2C Communication
The SC606 interface uses a limited version of the combined
format protocol as described in the Phillips I2C Bus Specification
version 2.1. With this format, the Start condition and the Slave
Address are both repeated. Data formatting must be a single byte
only. Note that the SC606 can only operate on an I2C bus using
the limited combined format protocol. If any other I2C data
formatting is used on the bus the SC606 may exhibit false
acknowleges to the commands. The I2C Slave Address is
1100110. I2C Fast Mode is supported at 400kbit/s. For more
information about the I2C combined protocol refer to the I2C Bus
Specification from Philips Semiconductors.
Slave Address
Following a start condition, the bus master outputs the address
of a slave device. The 7 bit slave address for the SC606 is
1100110. The address is followed by a least significant bit (LSB).
The LSB determines the data direction.
