说明

AW35019A is a smart e-Fuse with robust overcurrent and overvoltage protection. The wide operating voltage allows control of many popular DC buses.
AW35019A uses N-channel MOSFET as power switch, and allows the user to program the current-limit threshold between 250mA to 3A with an external resistor when the load exceeds the current-limit threshold.
AW35019A can withstand 24V DC voltage. In the event that an incorrect voltage is ＩＮ, the output clamps to 5.4V to protect the load. If the voltage at ＩＮ exceeds 7.5V, the device disconnects the load to prevent damage to the device and/in load.
Additional features include enable, under-voltage, over-temperature, output discharge and fault flag output are provided to monitor system status.
