MC33887DH

MC33887DH is a motor driver controller from the PMIC family which is designed for automotive, industrial, and home appliance applications. The MC33887DH is an intelligent, robust solution that implements dual, full-bridge drivers and advanced low-side power switches with protection features such as short protection, thermal overload protection, and reverse battery protection.

The driver circuit uses the MC33887DH’s integrated logic to provide high-current and high-voltage outputs in order to quickly and safely control both small and large motors. It is designed to switch large inductive loads with extreme precision and low energy losses. The MC33887DH offers an adjustable speed range and a variety of output signals to ensure that the motor is driven properly.

The MC33887DH has two full-bridge drivers which provide the necessary current for controlling a motor. The forward/reverse logic is implemented using the two PWM outputs. The user can adjust the speed of the motor using the speed control PWM input and the MC33887DH will regulate the speed output accordingly. It also has a speed monitor output which provides feedback to the user on the actual speed of the motor.

The MC33887DH has several protection features which make it suitable for automotive, industrial and home appliance applications. It has a built-in over-temperature protection which will shut down the circuit and protect the motor from overheating. It also has a reverse battery protection which prevents damage to the motor and controller in case of a reversed voltage connection. The MC33887DH also has a short protection which protects the circuit from potential shorts due to faulty wiring and overcurrent.

The MC33887DH has several applications in the automotive, industrial, and home appliance sectors. In the automotive sector, the MC33887DH can be used to control electric and hydraulic motor actuators for window lifts, mirror adjustment, seat adjusters, HVAC, wipers, and other applications. In the industrial sector, the MC33887DH can be used to control pumps and other motors as well as industrial lights and other automation applications. In the home appliance sector, the MC33887DH can be used to control ventilation and air conditioning systems, refrigerator motors, washing machine motors, dishwashers, and other applications.

In conclusion, the MC33887DH is an intelligent, robust motor driver controller which is designed for automotive, industrial and home appliance applications. It has a wide range of features such as short protection, thermal overload protection and reverse battery protection. It has an adjustable speed range, forward/reverse logic and a speed monitor output to ensure that the motor is driven properly. It is suitable for a wide range of applications in the automotive, industrial, and home appliance sectors.
