Abstract

A power control circuit for a vehicle includes a power switch, N-type semiconductor switches electrically connected between a power supply terminal to which an input voltage is applied and the power switch and in which the N-type semiconductor switches are connected back-to-back, a charge pump circuit for generating a drive voltage to drive the N-type semiconductor switches by boosting the input voltage, a reverse voltage protection circuit electrically connected between an output terminal of the charge pump circuit and a node in which the N-type semiconductor switches are connected to each other, a microcontroller for generating a pulse width modulation signal for the operation of the charge pump circuit, and a voltage attenuation circuit for attenuating the drive voltage and applying the attenuated drive voltage to the microcontroller.
