Description

The AW9364B is a 4-channel ultra low dropout constant-source parallel LED driver. With the pro-prietary Q-MirrorTM technique, the AW9364B uses an internal resistor to set the bias current for four LEDs, which are matched to ±5%. The AW9364B incor-porates a single wire interface to program the output current at 16 continuous steps. The AW9364B has an internal deglitch circuit for filtering the noise of the EN input.
The AW9364B requires only a 50mV dropout voltage at a 20mA load. The feature makes AW9364B ideal for battery-operated systems, such as personal digital assistants.
The AW9364B is available in DFN 2mm x2mm x0.75mm-8L package and is specified over the -40°C to +85°C temperature range.
