Semiconductor device, power supply system, and vehicle

Abstract

A semiconductor device (1) includes: multiple channels of power supply circuits (51 to 57); a first input part (EN terminal) configured to input a first input signal; and a second input part (ADDEN1 terminal or I2C communication terminal) configured to input a second input signal, and is configured to be capable of setting allocation of the channels of the power supply circuits to each of an enable function using the first input signal and an additional enable function using the second input signal, first delay time information related to an elapsed time from when the first input signal indicating startup is input until the channel allocated to the enable function starts up, and second delay time information related to an elapsed time from when the second input signal indicating startup is input until the channel allocated to the additional enable function starts up.
