A CIRCUIT, CORRESPONDING SYSTEM, VEHICLE AND METHOD OF OPERATION

A driver circuit (30) comprises a power supply pin (300) configured to receive a power supply voltage (Vs), and a set of control pins (302a, 302b, 304a, 304b) configured to provide a set of control signals for controlling the switching activity of a set of switches of an h-bridge circuit. The set of switches of the h-bridge circuit comprises a pair of high-side switches and a pair of low-side switches. [0002] The driver circuit (30) comprises control circuitry (36) coupled (32a, 32b, 34a, 34b) to the control pins (302a, 302b, 304a, 304b) and configured to generate the control signals, and sensing circuitry (38, 360) coupled to the power supply pin (300) and configured to generate a detection signal indicative of said power supply voltage (Vs) exceeding a threshold value. [0003] The control circuitry (36) is sensitive to the detection signal and is configured to generate said control signals to activate one of said pair of high-side switches and said pair of low-side switches and deactivate the other of said pair of high-side switches and said pair of low-side switches as a result of said detection signal being indicative of said power supply voltage (Vs) exceeding said threshold value.
