Abstract

See full text

An apparatus includes an integrated circuit that includes low side power supply circuitry that provides an output voltage for H-bridge circuitry. The low side power supply circuitry includes one transistor that provides one current to the output of the low side power supply circuitry in response to the output voltage of the low side power supply circuitry dropping below a quiescent level. The low side power supply circuitry also includes a second transistor that controls the conduction state of a third transistor, based at least in part, upon the first transistor providing the first current to the output of the low side power supply circuitry. The third transistor provides a second current to the output of the low side power supply circuitry.
