TPS2066: Higher output voltage than input voltage

Nicholas Carley

Part Number: TPS2066

What happens if OUT1 or OUT2 is driven externally by mistake and the driving voltage is higher than the input voltage, will it back drive the IN pin?

HI Nicholas,

If the device is disabled, then the power switch is block.

If the device is enabled, then the current will flow from OUT to IN.

Best regards,

Feifei

If the device is unpowered and Vout>Vin does it still block reverse current?

If unpowered, VIN=0V or EN=0V, will block reverse current.
