AW9358QNR

The AW9358 is an 8-channel parallel white LED driver with ultra low dropout constant-current source. The AW9358 can drive 8 LEDs and each LED’s maximum current is up to 20mA which is set by the internal resistor. The proprietary Q-MirrorTM technique is used in the AW9358, which makes the 8 LEDs current matching to ±1%. The AW9358 use 1-Wire Brightness Control, 16-Step Linear Scale LED Brightness Control, which effectively avoid the interference caused by the PWM dimming mode.

The AW9358 has an internal deglitch circuit can effectively eliminate the influence of the glitch signal for EN input. The AW9358 requires only a 50mV (typical) dropout voltage at a 20mA load. The feature makes AW9358 ideal for battery-operated systems, such as personal digital assistants. The AW9358 only need one ceramic capacitor making the system design easier, and use less PCB. The shutdown current of the AW9358 is less than 0.1uA.

The AW9358 is available in a small TQFN3mmx3mm-16L package and is specified over the -40℃ to +85℃ temperature range.
