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.

Abstract: This disclosure describes circuits and techniques for identifying potential problems with control signals for power switches. More specifically, this disclosure describes the use of registers, e.g., volatile or non-volatile storage elements, configured to count the rising and/or falling edges of pulse modulation (PM) signals within driver circuits or other control circuits. By counting the edges of PM signals within driver circuits, signaling problems can be identified based on mismatch between different counters. The techniques may be used by a driver circuit to detect circuit problems, or readout of the registers can be done after device failure, in order to help identify whether signaling problems may have caused the device failure.
