Abstract
A write driver to supply current to an induction load, including an H-bridge circuit coupled to the induction load to switch the current between a first current path and a second current path, said induction load operative to generate an undershoot current, and an undershoot circuit to control the undershoot current based on a comparison of a reference voltage and a flyback voltage. The undershoot circuit is connected to bases of the transistors of the lower H-bridge circuit.
