TPS1H100-Q1: Loss of Power Supply Protection

Part Number:TPS1H100-Q1

Hi team,

I have a question about Loss of Power Suply Protection.

There is a description of Loss of power supply protection in the data sheet, is this a problem unique to this device?

It occurs when the power supply is lost in the case of an inductive load, so I do not think that it is a device specific problem.

According to the data sheet, additional parts are required for GND network and MCU communication line.

For example, if e-fuse TPS2660, will this measure be unnecessary?

Our customer needs a switch with protection function to supply power from the ECU to the outside.

The power supply is 24 V and the load current is about 100 mA, so Automotive is not necessary.

Best regards,

Tomoaki Yoshida
