摘要： A power-on-detection (POD) circuit includes first and second comparators, a voltage divider, a detection circuit coupled to a first voltage source node and the voltage divider, and logic circuitry coupled to outputs of the first and second comparators. The detection circuit outputs a control signal identifying if a first voltage source node has a voltage potential that is higher than ground. The control signal turns on and off the first and second comparators, which are respectively coupled to first and second nodes of the voltage divider and to a reference voltage node. The logic circuitry outputs a power identification signal based on the signals received from the outputs of the first and second comparators.
