TPS25981: Parallel Configuration

Part Number: TPS25981

Hello,

TPS25981's data sheet has a picture of two TPS25981s' parallel configuration in Figure 9-2 on page 32, and a TPS25981's PG output goes to the other one's EN/UVLO input. A simulation result of this configuration shows a glitch at the second TPS25981's PG output, and I wouldn't like to use this connection.

Can it be an issue if the two TPS25981 devices share the same EN/UVLO signal and the same PG one?

Best regards,
Shinichi Yokota
