TPS4H000-Q1: how to realize 3 output with TPS4H000

Hale Tan

Part Number: TPS4H000-Q1

Hi team,

The customer wanted to use TPS4H000-Q1 3 output with short to gnd detection and open load detection. Can the last output be float? Or do you have any other advice to meet the customer requirement?

Hi Hale,

It is possible to leave the fourth output floating. The customer can also pull IN4 to GND.

Thanks,

Hi Shreyas,

Thanks. And if the fourth output is floating, can I also leave the IN4 floating?

Hi Hale,

Yes it is possible to do so as the INx pin has an internal pull down. But it is also okay to connect INx to GND through a external pulldown.

Thanks,

Shreyas
