Hi Sir,
may we know the impedance value of internal alert pin? maybe is open drain MOSFET rds_on?
also, how many Ohm in 80 deg and 95 deg? at alert pin.

Dear Tommy -
The ALERT pin is open drain, which means it will be high impedance when off (and pulled up to VCC via an external resistor) and low impedance (GND potential) when on (switched).
Hi Tommy,
The TMP102 ALERT pin is rated to maintain 0.4V max while sinking 3mA. Under this worst-case condition, the output impedance is about 133ohms.
thanks,
