Abstract

Supply voltage switching circuitry that is configured to dynamically switch between a battery supply voltage and a boost supply voltage, that is generated from the battery supply voltage, to power half-bridge driver circuitry based on an on-going evaluation of one or more system parameters. The supply voltage switching circuitry is configured to deliver the boost supply voltage to high-side driver circuitry. The supply voltage switching circuitry is configured to select between delivering the boost supply voltage to low-side driver circuitry and delivering the battery supply voltage to low-side driver circuitry.
