MC33931EKR2 Typical application Circuitry

MC33931EKR2

The MC33931EKR2 is a monolithic H-Bridge Power IC, primarily designed for automotive applications and motor control systems.

Application Scenarios: The MC33931EKR2 is widely used in automotive environments for controlling DC motors, such as in power steering, engine cooling fans, and window lifters. It's also applicable in robotics and industrial control systems.

Key Features: This IC can handle high current loads and is equipped with features like overcurrent protection, thermal shutdown, and under-voltage shutdown. It's capable of operating over a broad temperature range, making it suitable for harsh automotive environments.

Circuit Design Example – Automotive Window Lifter Control:

1. Power Supply Connection: Connect a 12V automotive battery or power source to pin 20 (VBAT) of the MC33931EKR2. This pin provides the power for the H-Bridge.

2. Grounding the IC: Connect pin 1 (GND) of the MC33931EKR2 to the system's ground. This is essential for stable operation and noise reduction.

3. Motor Connection: Attach the motor leads to pins 8 and 13 (OUT1 and OUT2). The MC33931EKR2 drives the motor by switching these outputs.

4. Motor Direction Control Input: To control the motor direction, connect a microcontroller output to pins 3 (IN1) and 4 (IN2) of the MC33931EKR2. The polarity of the voltage supplied to the motor is determined by these pins.

5. PWM Speed Control: Connect a PWM signal from the microcontroller to pin 5 (INH) for speed control of the motor. This pin enables the PWM control of the H-Bridge.

6. Current Sensing Output: Pin 6 (CSOUT) can be used to monitor current and provide feedback on the load situation of the motor when linked to an ADC input of a microcontroller.

7. Enable and Disable the H-Bridge: Connect pin 2 (EN) to a digital output of the microcontroller. Setting this pin high enables the H-Bridge, while low disables it.

8. Voltage Sensing and Protection: Pins 16 and 19 (FS/RST and VDD) are for fault status reporting and under-voltage detection. Connect these to the microcontroller for monitoring the IC's status.

Design Considerations: When designing with the MC33931EKR2, consider the power supply requirements, motor characteristics, control logic for motor direction, PWM frequency for speed control, and current sensing for feedback. It's also important to include protective measures for overcurrent and thermal conditions.

In summary, the MC33931EKR2 is critical in applications like automotive window lifters, where robust motor control is needed. The circuit implementation involves careful planning regarding power supply, motor connections, control interfaces, and safety features for effective and reliable operation.
