ABSTRACT:
A switching circuit has a pull-up FET and a pull-down FET coupled to a load circuit, each FET having a control terminal coupled to a current regulating circuit. The current regulating circuit provides a high predetermined current for a relatively short duration to the gates of the FETs to quickly turn on or turn off the FETs. After the short duration, a low quiescent current is applied to the gates to maintain the FETs in their present states. An inhibiting circuit, coupled between the pull-up FET and the pull-down FET, detects the states of the FETs and delays turn-on of one FET until the other FET has turned off. An overcurrent circuit monitors a current through a switching FET and turns off the FET after a predetermined time delay when an overcurrent condition is detected. The overcurrent circuit then turns on the FET after another predetermined time delay.
