AW21018C is a 18-channel high precision constant current LED driver. r. The maximum current of each channel is recommended to be configured via external resistor REXT.
AW21018C can be turned off with minimum current consumption by pulling the EN pin low. When EN pin pull high and all LEDs off >30ms, AW21018C enters power save mode.
AW21018C is available in QFN 4mm x 4mm x 0.85mm-32L package. It operates from 2.7V to 5.5V over the temperature range of -40℃ to 105℃.
