Hi,
We are planning to use LM57 in one our application.
The application works from -55 deg C. LM57 will act as thermostatic switch in our application.
Tover threshold = -35 degC.
when temperature < -35 degC , Tover#(Open drain) will not be driven (default HIGH) which turns ON a heater(basically resister n/w).
When temperature > -35degC Tover# will be driven LOW and Turns OFF the heater.
The operating temperature of LM57 is below.
Can the LM57 behavior can be estimated for -50 °C to -55 °C temperature range?
---> When ambient temperature < -35 degC ( -55 degC to -35 degC ) Tover#(active LOW) should be driven LOW. Whether this can be achieved.
