TPS27081A: TPS27081A input power reverse protection.

Woody Cheng

Part Number: TPS27081A

Tool/software:

I would like to ask, if a 100K resistor is connected to GND at the (ON/OFF) pin of the TPS27081A, will the TPS27081A be in an open-circuit state when the input power is reversed?

Hello Woody,

100K at ON pin is like pull down resistance which will make sure ON pin is connected to GND when supply is floating.

When Input supply is reversed and ON pin voltage is low, device will be OFF.

Thanks
