TLIN1028-Q1: Schottky diode between Vsup and VBAT

Louis Lo

Part Number: TLIN1028-Q1
Other Parts Discussed in Thread: LM74722-Q1

If my system's VBAT main input already has reverse polarity protection using LM74722-Q1, do customer still need to add a Schottky diode between Vsup and VBAT?

The purpose of that diode would be to block reverse currents. If you already have this protection, you do not need to add the diode.
