AW26024E/AW26018E is a 24/18-channel high precision constant current LED driver. AW26024E/AW26018E supports 5-bit globe current control. 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.
AW26024E/AW26018E supports Auto-Breath-Pattern and has a flexible and efficient lighting effect programming function, which can reduce the resource occupation of the main controller.
AW26024E/AW26018E can be turned off with minimum current consumption by pulling the EN pin low. When EN pin pull high and all LEDs off >30ms, AW26024E/AW26018E enters power save mode.
AW26024E/AW26018E 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℃.
