Abstract
A gate driver is described for driving switches. The gate driver includes an input for receiving a signal indicative of a polarity of a voltage or current, and outputs for outputting gate signals for driving the switches. In response to a fault condition, the gate driver generates gate signals at the outputs that depend on the polarity of the voltage or current.
