6-Channel 1-wire Dimming LED Driver with Ultra Low Dropout Current Source

The AW9356 is a 6-channel ultra low dropout constant- source parallel LED driver. With the proprietary Q- Mirror TM technique, the AW9356 uses an internal resistor to set the bias current for four LEDs, which are matched to ±1%. The AW9356 incorporates a single wire interface to program the output current at 16 continuous steps. The AW9356 has an internal deglitch circuit for filtering the noise of the EN input. The AW9356 requires only a 50mV dropout voltage at a 20mA load. The feature makes AW9356 ideal for battery-operated systems, such as personal digital assistants. The AW9356 is specified over the -40℃ to +85℃ temperature range.
