AW26024 is a 24-channel high precision constant current LED driver. Each channel integrates independent 12-bit PWM generator which is composed of 8-bit brightness register and 8-bit color register. The maximum current of each channel is recommended to be configured via external resistor REXT.
AW26024 can be turned off with minimum current consumption by pulling the EN pin low. When EN pin pull high and all LEDs off >30ms, AW26024 enters power save mode.
AW26024 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℃.
