The HVIC integrates a 600V withstand voltage component and a 30V withstand voltage component on a single chip to drive a half-bridge or full-bridge MOSFET or IGBT. The driving circuit of the upper arm and the lower arm, the power supply undervoltage protection circuit, the signal interlock circuit, and the overcurrent protection circuit are built in the chip, so that the logic circuit such as the microprocessor can be directly driven and controlled without the use of the optical coupling.
