Hi team,

My customer is using the TPS2113A now, when remove VBAT_DC_5V, 5V_Cap will sink the current to IN1, we want to check whether the phenomenon is right or not. Thanks

Hi Frank,

Can you provide a bit more information here? Is the problem that the voltage on IN1 is not dropping when the power supply is disconnected? Has the device switched over to IN2 before current begins to flow from IN2 to IN1? This device has reverse current blocking from OUT to IN, so we do expect the device to block this current.

Thanks,

Yes, when remove the IN1，the voltage doesn't drop. And we have switched to IN2 before. It looks like IN2 go to IN1.
