The VWM350-0075P is a silicon monolithic integrated circuit designed for use as a driver for permanent magnet motors in car window lifter applications. It is a three channel power transistor array that combines the reliability and power efficiency of single-ended motor drives with the cost-effectiveness of bi-polar motor drives. The three channels are uniquely integrated together to form a single power device that is capable of both controlling the position and motion of a window lifter motor, while providing the necessary current and power to drive the motor.

The VWM350-0075P is a FET (Field Effect Transistor) array. It is a hybrid technology device which combines a MOSFET (Metal-Oxide Semi-conductor Field Effect Transistor) and a power transistor in a single package. The Power MOSFET acts as the main current generator, while the power transistor monitors the voltage drop across the MOSFET, allowing for precise control over the motor speed. The integrated circuit provides four distinct control signals – a high-side control signal and a low-side control signal for each channel.

The VWM350-0075P works by applying a small electrical signal to the control terminals, which cause the power MOSFETs to turn on and off. When the MOSFETs are on, a current is passed through the power transistor, which turns on the motor. The current and power required to drive the motor are monitored by the power transistor, which in turn adjusts the voltage applied to the MOSFETs by adjusting the duty cycle of the control signals. When the MOSFETs are off, the voltage applied to the motor is reduced, causing the motor to slow down or stop.

The VWM350-0075P’s power and control signals are strong and efficient, allowing it to drive motors up to 6 amps and 50V in continuous mode. The device is also extremely efficient, and can operate at up to 98% efficiency at low levels of current consumption. The wide 4.5V to 40V operating voltage range allows it to be used in a variety of applications, including car window lifters.

The VWM350-0075P is an ideal solution for car window lifter applications, offering precise motor control and a high level of efficiency. By combining the reliability and power efficiency of single-ended motor drives and the cost-effectiveness of bi-polar motor drives, it is an ideal choice for window lifter applications. It is also an excellent choice for other motor-driven applications that require precise motor control with high levels of efficiency.
