AW36423FCR

Inductorless, Dual Channel 1.0A Flash LED Driver

The AW36423 is a inductorless dual channel 1.0A flash LED driver that provides a high level of adjustability within a ultra-small solution size. The AW36423 includes two current sources which is controlled  independently  by  I 2 C-compatible interface. The AW36423 provides IVFM protection mode to prevent system reset or shutdown under low battery condition. The AW36423 is controlled via an I 2 C-compatible interface. The main features of the AW36423 include: flash / torch / IR current, flash timeout duration and IVFM. The AW36423 also provides hardware flash pin (STROBE) to control flash event. The device operates over a –40°C to +85°C ambient temperature range.
