Abstract

See full text

A power transistor overcurrent protection circuit includes an overcurrent detection circuit, a timing control circuit, and an enable control circuit. The overcurrent detection circuit is configured to detect whether there is an overcurrent flowing in the controlled power transistor. The timing control circuit and the enable control circuit jointly control the controlled power transistor. The power transistor overcurrent protection circuit can turn off the controlled power transistor so as to protect the controlled power transistor when there is an overcurrent flowing in the controlled power transistor for controlling a load to work or not to work.
