MC33982CHFKR2

Overview

The MC33982CHFKR2 is a dual H-bridge motor driver IC designed for automotive applications. It integrates two high-current half-bridges capable of driving brushed DC motors, solenoids, or lamps. The device features a wide supply voltage range and includes comprehensive protection mechanisms such as over-temperature shutdown, short-circuit protection, and undervoltage lockout. It supports PWM control for speed regulation and direction control, making it suitable for power window, seat adjustment, and wiper systems.

Feature Summary

• Dual integrated H-bridge architecture for independent motor control
• Integrated protection against thermal overload and output short circuits
• Supports pulse-width modulation (PWM) for precise speed and torque management
• Designed for robust automotive electrical environments

Applications

• Automotive power window actuators
• Seat position adjustment motors
• Windshield wiper and washer pump drivers
• General purpose brushed DC motor control in vehicles

Procurement Notes

Verify the specific suffix 'CHFKR2' against the manufacturer's current datasheet to confirm package type, tape-and-reel specifications, and regional compliance markings. Ensure the ordering part number matches the exact pin configuration and temperature grade required for the target automotive assembly. Cross-reference with official NXP distribution channels for authenticity.

Selection Notes

Select this component when a single IC solution is needed to drive two separate brushed DC motors or loads in an automotive environment. It is appropriate for designs requiring integrated fault protection and high current handling without external discrete switching components. Consider thermal dissipation requirements based on the expected load current and ambient operating conditions.

Part Context

This part belongs to the MC339xx series of automotive motor drivers from NXP Semiconductors. This family is widely used in body electronics modules where reliable actuation of mechanical components is critical. The MC33982 specifically targets applications needing dual-channel control within a compact footprint, reducing board space compared to discrete solutions.

Replacement Considerations

Check for direct cross-reference part numbers from NXP or other qualified automotive suppliers that match the pinout and electrical characteristics. Verify that any substitute meets the same AEC-Q100 reliability standards and functional safety requirements if applicable to the original design.
