Abstract: Overload detection and protection for power switch circuits. For circuits with faster switching speed, fast fault detection and response to a detected overload condition may be desirable. Detection circuitry may monitor a voltage on the control terminal of one or more power switches. Based on empirical measurements, in an overload condition of a power switch circuit, e.g., a half-bridge circuit, the voltage at the control terminal may increase, and in some examples, increase to a magnitude that is greater than a supply voltage. A comparator may detect a voltage increase that exceeds a voltage magnitude threshold, output an indication to control circuitry for the power switch circuit, and the control circuitry may take action to protect the rest of the circuitry, such as reduce voltage or shut off the power switch circuit.
