Abstract

A method of controlling a power supply to a semiconductor device including a first region having a high-side drive circuit, a second region having a signal processing circuit, a low-side drive circuit and a voltage control circuit, and a separation region formed between the first and second regions and having a rectifying element, includes turning on a first control signal to the voltage control circuit, turning off the first control signal to the voltage control circuit, and repeating the turning on of the first control signal and the turning off the first control signal.
