TPS22925: TPS22925 - Maximum ratings of Vout?

V Reuter

Part Number: TPS22925
Other Parts Discussed in Thread: TPS22953

Hi,

I normally wanna use the TPS22925 with a battery of 3.6 volts, but I have a additional USB plug in my device. So when the USB cable is plugged, it will turn off the TPS22925 directly and the 5 volts of the USB will be the power source for the load. Now the reverse current blocking of the TPS22925 turns on. My question is, if it is alright to have 5 volts (or a bit more) of the USB at Vout when the TPS22925 is turned off?

Best regards and thank you

    Hi VR, 

    Thanks for reaching out on E2E!

    Would a device like the TPS22953 work better? This device can support 5V and has the same reverse current blocking functionality as the TPS22925 (RCB only when disabled)

    Thanks,
