Claim 4:
5. The circuit of claim 1, in which the PWM controller has a PWM controller input, and wherein:
in response to a PWM input signal on the PWM controller input having a first logic state, the PWM controller implements the repeating pattern comprising the first, second, third, and fourth pattern portions; and
in response to a PWM input signal on the PWM controller input having a second logic state, the PWM controller implements the repeating pattern until a current through at least one of the first, second, third, and fourth transistors exceeds a threshold at which time the first, second, third, and fourth gate drivers turn off the first, second, third, and fourth transistors, respectively.
