General Description
The ET9902 is a high voltage, high current, bidirectional switch. It provides input over-voltage and surge protection as well as reverse-blocking of output voltage. The logic control of the device is designed to interact with both the system controller and the wireless charging receiver which allows creating a dual input charger application with a single switch.
