The AW36413 is a dual LED flash driver that provides a high level of adjustability within a small solution size. The AW36413 utilizes a 2MHz in 4MHz fixed-frequency synchronous boost converter to provide power to the dual 1.5A constant current LED sources. The dual 128 levels current sources provide the flexibility to adjust the current of LED1 and LED2 in Flash/Torch/IR modes. The total allowed LED Current during operation is 1.5A (ILED1+ILED2≤1.5A). The AW36413 provides three IVFM protection modes to prevent system reset in shutdown under low battery condition.
The AW36413 is controlled via an I2C-compatible interface. The main features of the AW36413 include: flash/torch current, flash timeout duration, IVFM, TX interrupt, and NTC thermistor monitor. The AW36413 also provides hardware flash and hardware torch pins (STROBE and TORCH/TEMP) to control Flash/Torch events.
The 2MHz in 4MHz switching frequency options, overvoltage protection (OVP), and adjustable current limit allow for the use of tiny, low-profile inductors and 10-µF ceramic capacitors. The device operates over a –40°C to +85°C ambient temperature range.
The AW36413 is available in small 0.4mm pitch 1.626mm×1.332mm CSP-12 package.
