Part Number: TPS2662

Hi Team,

Our customer want use TPS2662 as load swith of USB, but some times 24V power will missing touch to the output of USB, and some time the USB is now powered, we know that TPS2662 can block reverse current if TPS2662 is power on, but question is Can TPS2662 block current from output to input if it`s power off?

Thanks.

Hello Sunny

TPS2662 can block reverse current when input is not present. When input voltage is off, the internal blocking FET and high side FET remains off and the back to back body diode structure should prevent reverse current when voltage is present on output pin.

Thanks & Regards
