Abstract

An H-bridge circuit includes a lower-arm field-effect transistor and a current supplying element that turns on when the drain of the lower-arm field-effect transistor is negatively biased due to regenerative current. When turned on, the current supplying element conducts current from the source to the drain of the lower-arm field-effect transistor, in parallel with a parasitic diode inherent in the lower-arm field effect transistor. The current supplying element competes with other parasitic elements that conduct current from peripheral circuitry to the drain of the lower-arm field-effect transistor, thereby reducing the amount of such current drawn through the peripheral circuitry and lessening the impact of the regenerative current on the peripheral circuits.
