Low Noise Smart LED www..com Driver with Serial Interface
POWER MANAGEMENT Description
The SC606 is a very high efficiency charge pump white/color LED driver from the mAhXLifeTM family of products. It is optimized for Li-Ion battery applications. The LED current is regulated to a value configured by the user through an I2C compatible serial interface. 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.

POWER MANAGEMENT Applications Information
Detailed Description 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. 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 10F. The charge pump does not switch during 1x mode, saving power and improving efficiency. 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. 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. 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, VF , be under 250mV. 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. Mode transition voltages VTRANS1X and VTRANS1.5X can be estimated by the following equations:
www..com
VTRANS1X = VF + VILEDn +(# of LEDs used) ILED 0.83 VTRANS1.5X = [VF + VILEDn +(# of LEDs used) ILED 10.1]/1.5 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.
= [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 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. (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 = 80A with Enable = High. This is the lowest power state while Enable = High. 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, ILED-ERR[%] =
ILED(measured) - ILED ILED

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.
