TPS25947: spec check

GARETH OU

Part Number: TPS25947

Customers will consider using TPS25947X instead of LM73100 for three sets of 19V voltage Oring architecture. Is it feasible?

It seems that TPS259472 has OVP limitation, TPS259470 is more suitable, right?

What is the difference between AUX OFF and PG?

Hi Gareth,

For ORing we recommend TPS259470 .

AUX off is available in TPS259470 device for purpose of power muxing. PG is available in TPS259472/74 device for monitoring power rail. Please read datasheet section 8.3.10 Auxiliary Channel Control (AUXOFF) and 8.3.11 Power Good Indication (PG) for detailed understanding.
