TPS1H100-Q1: Sizing of ground resistor and diode

Viktorija Cecil

Part Number: TPS1H100-Q1

Regarding the GND pin> Do you have a guide how to size the RGND resistor and the diode? Can this pin be connected directly to GND?

Thanks

Hi Viktorija,

The recommended resistor is a 1-kOhm resistor in parallel with a diode with a forward current greater than 100-mA diode. If you have upstream power protection such as an ideal diode on the VS pin, you can tie it directly to GND.
