MC33486ADH is a dual high-voltage active-clamp synchronous H-bridge driver designed for bidirectional motor control applications. It is used in a wide range of motor control applications including automotive, agricultural, consumer, and industrial applications where voltage and current requirements exceed the capabilities of off-the-shelf motor drivers. The MC33486ADH is a high performance H-bridge driver specifically designed for driving dc brushed motors in bidirectional two-phase or three-phase mode. It consists of two full bridges connected to the motor to provide bidirectional motor control. It features an adjustable dead-time to minimise motor switching losses and provide precise motor control.

The MC33486ADH motor controls the electrical motor by applying high voltage switching signals to its terminals. The motor has two or three terminals, an A and B or A, B and C respectively. These two/three terminals are alternately supplied with a positive and negative voltage to switch the electrical motor on and off. The motor will therefore rotate continuously when the MC33486ADH receives the correct sequence of voltages.

The MC33486ADH has two integrated power switches capable of switching up to 20V and up to 20A current each. Additionally, it has a protection circuit, including an over-current, over-temperature, under-voltage and over-voltage protection system, to ensure safe operation of the motor. The MC33486ADH also has three integrated Hall Effect sensors that monitor the motor speed and position, if fitted. This allows for precise motor control, as the MC33486ADH can be used to adjust the motor speed and direction.

The MC33486ADH can be used in automotive, agriculture, consumer, and industrial applications. It can be used to control electric window lifts, robotic actuators and valves, pumps, motors, and power tools. It is especially suitable for applications where torque and vibration are important, as it can provide precise control to the motor. The MC33486ADH is also suitable for applications where high voltage and high current are required and safety features are important. In addition, it is recommended for use in applications where space is at a premium, as it is designed in a compact, space-saving package.

In conclusion, the MC33486ADH is a high performance H-bridge driver specifically designed for driving dc brushed motors in bidirectional two-phase or three-phase mode. It has two integrated power switches capable of switching up to 20V and up to 20A current each and over-current, over-temperature, under-voltage and over-voltage protection system. The MC33486ADH is used in a wide range of motor control applications including automotive, agricultural, consumer, and industrial applications and is suitable for applications that require precise motor control, high voltage and high current capabilities, and safety features.
