Abstract
A chip programming voltage detection circuit and a chip programming voltage detection method are disclosed. The chip programming voltage detection circuit comprises a detection subcircuit and a warning subcircuit. The detection subcircuit detects a voltage at a programming voltage output pin, and outputs a detection signal based on the voltage at the programming voltage output pin. The warning subcircuit is connected to a detection output terminal of the detection subcircuit, and is operated to issue a warning alarm in a case where the detection signal indicates that the voltage at the programming voltage output pin does not reach a voltage required for an IC chip programming.
