It is also used in non-automotive applications such as lawnmowers, washing machines, industrial and HVAC systems, DC motors, pumps, and other industrial applications.

The combination of pre- and post diagnostic monitoring, fault protection, and over temperature shutdown along with highly integrated components make the MC33039DR2 ideal for use in automotive and non-automotive applications, as well as in harsh industrial conditions.

Working Principle

The MC33039DR2 is a two-phase, half-bridge motor driver with two output channels. It is designed to drive two DC motors in full wave bridge configuration. The MC33039DR2 can be operated in either speed or position control mode. It employs an external pot balance logic circuit to control the speed and position of the motor.

The MC33039DR2 provides speed control through the external pot circuit, wherein the maximum speed is adjustable through an external resistor connected between the REF pin and GND. It also provides position control through the external pot circuit, wherein the position is adjustable through an external reed sensor or pot connected between the REF pin and GND.

The MC33039DR2 also provides fault protection, wherein the circuit can detect over temperature conditions, short circuit conditions, over current conditions and open load conditions. It also provides status signals through LEDs, to indicate power on, motor on, service required, overload and fault conditions.

The MC33039DR2 also features highly integrated components, such as the Hall-effect latch and the proportional integrative and differential (PID) gain amplifier, which helps to reduce size and cost. The device also uses a high-frequency PWM system, which minimizes the inductance required for the output devices, thus permitting faster control and response.

The MC33039DR2 is a highly integrated device that provides robust and flexible motor control, making it a perfect choice for automotive and industrial applications. Its wide range of features make it suitable for use in a wide range of applications.
