Constant power active discharge of energy storage circuit

A circuit, comprising:

• a reference signal generator having first and second input terminals and an output terminal, the first input terminal of the reference signal generator configured to receive a discharge time select value indicating a discharge time, and the second input terminal of the reference signal generator configured to receive a stop voltage select value indicating a target voltage to discharge to within the discharge time;
• a comparator having first and second input terminals, and an output terminal, the first input terminal of the comparator configured to receive a sensed voltage, and the second input terminal of the comparator coupled to the output terminal of the reference signal generator;
• a one-shot circuit having first and second input terminals, and an output terminal, the first input terminal of the one-shot circuit coupled to the output terminal of the comparator, and the second input terminal of the one-shot circuit configured to receive an on-time value;
• and
• a gate driver having an input terminal and an output terminal, the input terminal of the gate driver coupled to the output terminal of the one-shot circuit.
