•Optimized Flash LED Current During Low Battery Conditions (IVFM)
•Hardware Strobe Enable (STROBE)
•400kHz I2C：AW36429（I2C Address=0x63）
•0.4mm Pitch，FCQFN-10L Package
The AW36429 is a inductorless four channel flash LED driver that provides a high level of adjustability within a ultra-small solution size. The AW36429 includes two current sources and two current sinks which are controlled independently by I2C-compatible interface. The AW36429 provides IVFM protection mode to prevent system reset in shutdown under low battery condition.
The AW36429 is controlled via an I2C-compatible interface. The main features of the AW36429 include: flash / torch / IR current, flash timeout duration and IVFM. The AW36429 also provides hardware flash pin (STROBE) to control flash event.
The device operates over a –40°C to +85°C ambient temperature range.
The AW36429 is available in small 0.4mm pitch 1.6mm×1.2mm FCQFN-10L package.
