Abstract
The application relates to voltage supply in switched-mode driver integrated circuit (IC). The IC has an output bridge with first and second circuit branches, where each of the circuit branches has an output node () connected between first and second transistor switches () for selectively connecting the output node to respective first and second voltages (VH, VL). There are discrete first and second IC die contacts () for receiving the first voltage, and the first and second circuit branches are connected to the first and second IC die contacts respectively. Ancillary circuitry () is configured to receive a supply voltage from a voltage supply node voltage which is connected to the first and second IC die contacts via respective first and second respectively matched resistances.
