Description

The AW36501 is a dual LED flash driver that provides a high level of adjustability within a small solution size. The AW36501 utilizes a 2MHz frequency synchronous boost converter to provide power to total 1.5A constant current LED sources. The chip support Flash mode and Movie/Torch mode, which can be configured with ENM and ENF enable pins. The maximum current of LED in Flash mode or Movie/Torch mode can be programmed by external resistors. The real LED current can be regulated through the PWM signal input from the ENM pin.
The AW36501 can improve single LED power by shorting two LED output sinks, up to 1.5A LED current for 660ms continuously. The integrated thermal regulation monitors the IC junction temperature and reduces the LED current in Flash mode to limit the IC’s temperature.
Multiple protection functions are integrated into the chip, including LED open or short protection, output over-voltage protection, cycle-by-cycle current limit protection and over-temperature protection. The chip consume less than 1A leakage current in shutdown. The AW36501 operates over -40°C to 85°C ambient temperature range.
The AW36501 is available in small 0.4mm pitch WBDFN 3mm×2mm×0.75mm -14L package.
