A system for controlling a directional indicator of a vehicle includes the directional indicator including a plurality of lamps turned on at different threshold voltages and indicating a turning direction of the vehicle. A controller is configured to change an input voltage that is supplied to the lamps to sequentially turn on/off the lamps.

Control apparatus of directional indicator lamp for vehicle and method thereof

A motor driving device for a vehicle includes a brushless DC (BLDC) motor driving device for optimizing electromagnetic compatibility (EMC). The motor driving device includes: a motor controller that controls driving of a motor in response to an operation of a switching element; and a drive semiconductor that controls a drive current of the motor controller in response to a predetermined register value, and controls electromagnetic compatibility (EMC) tuning by adjusting a switching time of the switching element in response to a drive current that is charged or discharged in or from the motor controller.

Motor driving device for vehicle

Disclosed herein is a Pulse Width Modulation (PWM) controller. The PWM controller includes a plurality of Field Effect Transistors (FETs) and an FET driver. A comparator compares a current flowing through the FETs with an overcurrent reference value, and microcomputer controls a motor and a circuit protection function, and turns off the FET driver when the current flowing through the FETs is greater than the overcurrent reference value as a result of comparison by the comparator.

Pulse width modulation controller

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.
