Abstract
Disclosed is an apparatus and method for controlling switching devices for a DC motor, which controls the dead-time in an on-chip manner, even when a microcontroller is not mounted in a vehicle controller, by providing a semiconductor chip for controlling switching devices for a DC motor. More specifically, switching devices are mounted in a semiconductor chip to configure an internal circuit of the chip with a half-bridge and a dead-time controller is provided on the semiconductor chip and is configured to transmit gating signals by controlling dead-time periods during operation of the switching devices and drive the switching devices directly connected to a motor.
