TPS22953: TPS22953 Reverse Current

Lawrence May

Part Number: TPS22953

I'm looking at using the TPS22953 for it's low leakage performance to isolate a rechargeable battery from my system during certain states. While ON, I need to be able to send both charging and discharging currents to the battery through this switch. I'm looking for clarification: does the TPS22953 support this type of bi-directional current flow in the ON state?

Thanks!

Hi Lawrence,

Thanks for reaching out on E2E.

Since the TPS22953 doesn't have always-on reverse current blocking, it can act like a bi-directional switch and charge / discharge the battery. When the device is off, it will block current from entering the device in both directions.

Thanks,

Arthur Huang

Thanks for the clarification Arthur, we'll look into getting a demo board and try it out.
