Abstract
An embodiment driver circuit comprises a power supply pin configured to receive a power supply voltage, and a set of control pins configured to provide a set of control signals for controlling switching of a set of switches of an h-bridge circuit comprising a pair of high-side switches and a pair of low-side switches. The driver circuit comprises control circuitry coupled to the control pins and configured to generate the control signals, and sensing circuitry coupled to the power supply pin and configured to generate a detection signal indicative of the power supply voltage exceeding a threshold value. The control circuitry is sensitive to the detection signal and is configured to generate the control signals to activate one of the pair of high-side switches and the pair of low-side switches and de-activate the other of the pair of high-side switches and the pair of low-side switches.
