TPS25942A: About PGOOD output when IN1 = 0V

Part Number: TPS25942A

We intend to cite the FIGURE79 circuit configuration in the TPS25942A data sheet.
Can the master PGOOD output drive the "priority signal" (slave OVP input) low when IN1 = 0V?

    Hi,

    Welcome to E2E!

    Yes, the device drives the "priority signal" LOW even when IN1 = 0V. We have an inbuilt circuit trick which draws power from the Vout to maintain "priority signal" LOW even when IN1 = 0V
