Abstract
A high voltage integrated circuit (HVIC) chip with a resistor connected between the substrate of the chip and ground. The resistor substantially improves the handling of negative voltage spikes by limiting the current passing through the intrinsic diode of the chip when the diode conducts due to negative transients at the output node.
