HIGH-SIDE DRIVER FOR PROVIDING AN OFF-STATE IN CASE OF GROUND LOSS

摘要

An electronic device has circuitry for driving a high side switch. The circuitry has a high side driver including a first switch and a second switch being coupled to each other by a driver output node. The driver output node is adapted to be coupled to a control input of the high side switch. The first switch is coupled to a driver high voltage level and the second switch is coupled to ground for alternately pulling the driver output node to either the driver high voltage level or to ground so as to turn the high side switch on and off. A diode element is coupled between the driver output node and the second switch in a forward direction from the driver output node to the switch.
