TC646VUA

PMIC - Motor Drivers, Controllers encompass a broad range of components and integrated circuits (ICs) that regulate the speed and power of electric motors. The TC646VUA is a Fast-Mode Plus (Fm+) I2C® Motor Controller specifically designed for automotive applications such as fan motors, blowers, windshield wipers, window lifter and power sliding doors.

The TC646VUA features a secondary side feedback line for accurate speed control and a Programmable Set Point for PWM dimming control. It is capable of driving up to 7A DC load current and features a protection circuit for overcurrent and over-temperature. It is AEC-Q100 qualified and available in a 3.2 x 3.2 mm QFN package with halogen free and lead-free options.

TC646VUA Application Field:

The TC646VUA is suitable for industrial applications such as cooling fans, blowers, air-conditioning motors and general purpose motor control. It is also used in automotive applications such as fan motors, blowers, windshield wipers, window lifter and power sliding doors.

TC646VUA Working Principle:

The TC646VUA is a motor controller that provides speed and power control for DC electric motors. It is designed to be used in automotive and industrial applications to control and regulate the speed and power of these motors. The TC646VUA is an I2C®-compatible device and uses an integrated power MOSFET and a secondary side feedback line for accurate speed control. It is capable of driving up to 7A DC load current and features a protection circuit for overcurrent and over-temperature. The TC646VUA also features a programmable set point for PWM dimming control.

When the TC646VUA is enabled, it uses the I2C® bus to receive commands from a controlling system. The TC646VUA then uses this data to adjust the output current and speed of the motor. The motor’s current and speed can also be regulated by using the programmable set point, allowing the motor to be dimmed or pulsed using a defined frequency and duty cycle.

The TC646VUA also includes a secondary side feedback line which provides information about the motor’s speed and current. This information is passed back to the controlling system, allowing it to adjust the output current and speed of the motor as needed.

Additionally, the TC646VUA features a protection circuit that can shut off the output current when it exceeds a preset threshold. This circuit also provides protection against over-temperature conditions, which can lead to motor damage.

Conclusion:

The TC646VUA is a Fast-Mode Plus (Fm+) I2C® Motor Controller specifically designed for automotive applications. It is capable of driving up to 7A DC load current and features a protection circuit for overcurrent and over-temperature. It is suitable for industrial applications such as cooling fans, blowers, air-conditioning motors and general purpose motor control, as well as automotive applications such as fan motors, blowers, windshield wipers, window lifter and power sliding doors. The TC646VUA also includes a secondary side feedback line which provides information about the motor’s speed and current, allowing the controlling system to adjust the output current and speed as needed.
