AW36514FCR数据手册Awinic中文资料规格书

描述 Description

The AW36514 is a dual LED flash driver that provides a high level of adjustability within a small solution size. The AW36514 utilizes a 2MHz in 4MHz fixed-frequency synchronous boost converter to provide power to the dual 1.5A constant current LED sources. The dual 256 levels current sources provide the flexibility to adjust the current of LED1 and LED2 in Flash/Torch/IR modes. The AW36514 provides IVFM protection to prevent system reset in shutdown under low battery condition. The AW36514 are controlled via an I2C - compatible interface. The main features of the AW36514 include: flash/torch current, flash timeout duration, IVFM and TX interrupt. The AW36514 also provides hardware flash/torch pin (STROBE/TORCH) 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 AW36514 is available in small 0.4mm pitch FCQFN 1.6mm×1.2mm×0.55mm -10L package.
