BD65494MUV-E2

PMIC - Motor Drivers, Controllers

BD65494MUV-E2 is a motor driver, controller integrated into a single large-scale integrated circuit (IC). The product is designed to coordinate the operation of two brushless DC motors, with built-in drive and control functions. This product is mainly used in home appliances, automotive and office automation (OA) equipment.

Application Field

BD65494MUV-E2 is mainly used in home appliances, automotive and office automation (OA) equipment applications. The main product characteristics include high reliability, low power consumption, and easy to use.

Working Principle

The BD65494MUV-E2 consists of a pre-driver with two H-bridge drivers, two 4-phase full-bridge drivers, and a controller unit. It can process logic level signals from external inputs, such as on/off (1/0) commands and PWM signals, to adjust motor speed. After the logic signals are processed into minimal signals and sent to full bridge drivers, they turn into motor control signals.

The controller unit reads \'power-on/reset\' data and monitors the motor control signals. When the motor is running, the controller unit processes the signals and adjusts the motor speed in response. When the motor stops running, the controller unit resets itself and waits for the next control signal.

The device also provides comprehensive protection functions, including over temperature protection, over current protection, and built-in watchdog to facilitate the operation of the motor, reduce the burden on users, and improve the reliability of the device.

Conclusion

The BD65494MUV-E2 is a motor controller, pre-driver and H-bridge driver integrated into a single IC package. It is mainly used in home appliances, automotive and OA equipment, and has characteristics of high reliability, low power consumption and easy to use. The device receives logic input signals to adjust the motor speed, and provides comprehensive protection functions.
