TPS25944L: Latching in Reverse Current Blocking

Hello Rakesh,

So the device won't latch off in this condition, but would the Fault signal out of ECB stayed latched low to indicate that there was a reverse current event?

We are trying figure out why the FLT signal is staying asserted low at power-up when it should go high.

Thank you,

Kyle

Hello Rakesh,

Thank you. Another quick question...

From TPS25944 spec:

• PGOOD is used to drive OVP
• PGOOD high is asserting OVP on the slave
• PGOOD low is enabling the slave to be active
• PGOOD is open drain driver
  i.e. The driver must be active/driving to assert power not good

Question:

• When IN1 is down (zero), how can the master drives PGOOD low?

Thank you,

Kyle
