Hi Steven,

Yes it's possible to use the INT pin in the circuit you have to turn on a PMOS. Can you explain the purpose of the circuit? INT pin can work with an NMOS as well and it can be configured open-drain or push-pull.

hanks for your reply !

I want to set int_pup to open-drain .

When the battery voltage is higher than 2.4V , INT Pin output to LO , Then p-mos turns on.

When the battery voltage is lower than 2.3V , INT Pin to HI-Z , Then p-mos turns off.

All I can think of is to set INT_PUP to 0 to open the drain.

INT_POL set 0 is active LO.

INT_TYPE set 0 is level-type.

INT Voltage Low Set Threshold = 2.3V.

INT Voltage Low Clear Threshold =2.4V.

Can it be used like this ?
