VNH5019ATR-E is a low-cost, high-efficiency, dual full-bridge driver specifically designed for automotive applications. It is an integrated board device that combines two high-current full-bridge MOSFET drivers with an integrated logic control circuit. This motor is suitable for automotive applications such as motor control, power window, power lock, windshield wiper, and heated seat. It also can act as a derivative DC brush motor driver or stepper motor driver, and can be used in a variety of other applications.

The main operating principles of the VNH5019ATR-E are that it is capable of implementing digital pulse width modulation (PWM) for controlling the two full-bridge MOSFET drivers. The device contains three main components, a logic control circuit, a current control and a voltage regulation. The logic control circuit sends control signals to the current control and then it sends control signals to the voltage regulation and finally to the two full-bridge MOSFET drivers. With current sensing, the logic control circuit is able to customize the speed and torque of the motor. The current control acts as a current regulator and is able to protect the driver from excessive current. The voltage regulation circuit keeps the voltage in a certain range, which further improves the motor's efficiency. Due to the presence of the logic control and current sensing, the VNH5019ATR-E can provide advanced features such as velocity feed-forward, ramp time setting, encoder emulation and compatible with many PID control algorithms.
