A method and apparatus is provided that combines bandgap trim, temperature sensor trim, comparator offset trim, and the setting of the temperature trip point. A comparator compares a bandgap reference voltage and temperature sensor voltage and trips the circuit when the temperature voltage is less than the bandgap reference voltage. The temperature voltage is combined with a compensating voltage to trim the circuit and set trip point. A method is provided to adjust the compensating voltage until the circuit trips at the any desired temperature.
