AW36529FCR

Inductorless, Four Channel Flash & Indicator 2in1 LED Driver

The AW36529 is a inductorless four channel flash & Indicator 2in1 LED driver that provides a high level of adjustability within a ultra-small solution size. The AW36529 includes two current sources and two current sinks which are controlled independently by I 2 C-compatible interface. The AW36529 provides IVFM protection mode to prevent system reset or shutdown under low battery condition. The AW36529 is controlled via an I 2 C-compatible interface. The main features of the AW36529 include: flash / torch / IR / Indicator current, flash timeout duration, IVFM and breath features. The AW36529 also provides hardware flash pin (STROBE) to control flash event. The device operates over a –40°C to +85°C ambient temperature range.
