ABSTRACT:
A circuit for detecting a brownout condition may include a temperature compensating circuit that provides a temperature compensated brownout reference voltage and an input signal to compare with the brownout reference voltage. Additionally, the detection circuit may include a comparator to generate a brownout indicator if the input signal crosses the brownout reference voltage. In certain implementations, the temperature compensating circuit has two branches connected in parallel. A first branch provides the reference voltage substantially independent of temperature, and a second branch provides the input signal, which is an indication of a supply voltage. The first branch is coupled to a first input of the comparator, and the second branch is coupled to a second input of the comparator. Additionally, the temperature compensating circuit may include a third branch that has components to adjust the reference voltage.
