Abstract
A method for protecting a system including a driver integrated circuit includes receiving a driver input signal. The method includes driving an output signal externally to the driver integrated circuit. The output signal is driven based on the driver input signal and an indication of a delay between receipt of an edge of the driver input signal and arrival of a corresponding edge of the output signal at an output node coupled to a terminal of the driver integrated circuit.

A method for protecting a system including a driver integrated circuit, the method comprising:
- generating one or more indications of whether one or more edges of a driver input signal are delayed in an output signal at an output node of the driver integrated circuit coupled to a terminal of the driver integrated circuit;
- generating an error signal based on the one or more indications;
- and
- in response to the error signal, adjusting driving of the output signal externally to the driver integrated circuit.
An driver integrated circuit comprising:
- a logic circuit configured to generate one or more indications of whether one or more edges a driver input signal are delayed in an output signal, and to generate an error signal based on the one or more indications;
- and
- a driver circuit configured to drive the output signal to a terminal of the driver integrated circuit based on a driver input signal and the error signal.
An electronics system comprising:
- a gate driver integrated circuit including a logic circuit configured to generate one or more indications of whether one or more edges a driver input signal are delayed in an output signal, and to generate an error signal based on the one or more indications, and further including a driver circuit configured to drive the output signal to a terminal of the gate driver integrated circuit based on the driver input signal and the error signal;
- and
- a drive transistor coupled to the terminal of the gate driver integrated circuit to receive the output signal.
