The NCP3902 is a high voltage, high current, bidirectional load switch. It provides input overvoltage 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.

• DC input voltage operating range from 3.0 V to 20 V
• Surge protection compliant with IEC61000-4-5 at 100 V
• Input voltage sense output with selectable clamp (16 V / 20 V)
