Abstract
A low-side driver circuit includes a low-side driver integrated circuit and a controllable switch. The low-side driver integrated circuit is responsive to an on-off command input signal to selectively operate in an ON mode and an OFF mode. The controllable switch is responsive to the on-off command signal to selectively operate in a CLOSED mode and an OPEN mode. The low-side driver integrated circuit and the controllable switch are configured to simultaneously operate in the ON mode and the CLOSED mode, respectively, and in the OFF mode and the OPEN mode, respectively. During a voltage transient the potential will be realized across the controllable switch, thus protecting the lower voltage rated low-side integrated circuit.
