MC33880DW

Overview

The MC33880DW is an octal half-bridge gate driver manufactured by NXP Semiconductors, designed for automotive engine control applications. It integrates eight high-side and low-side drivers in a single package. The device operates within a supply voltage range of 5.5 V to 24.5 V and delivers a peak output current of 2 A per channel. Key electrical characteristics include rise and fall times of 5 ns and a maximum dead time of 30 µs. It functions reliably across an extended temperature range from -40°C to +125°C and consumes 8 mA during operation.

Feature Summary

• Integrates eight independent half-bridge drivers for comprehensive load control
• Supports high-speed switching with 5 ns rise and fall times
• Includes programmable dead-time functionality to prevent shoot-through
• Designed for robust automotive environments with wide operating temperature range

Applications

• Motorcycle Engine Control Units (ECU)
• Small Engine Control Systems

• Electric Generators
• Marine Engines and Personal Watercraft

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm the specific suffix 'DW' corresponds to the SOIC-Wide-32 package variant required for your PCB layout. Check for moisture sensitivity levels and reflow soldering profile compliance before assembly. Ensure design-in documentation matches the exact part number to avoid functional mismatches with similar series components.

Selection Notes

Select this component when designing systems requiring multiple isolated half-bridge outputs for valve or injector control. It is suitable for applications needing fast switching speeds and integrated protection features. Consider the SOIC-Wide-32 package dimensions for thermal management and board space constraints. Evaluate the 2 A output capability against the specific load requirements of the connected actuators to ensure adequate drive strength without exceeding thermal limits.

Part Context

This component belongs to NXP's portfolio of analog and mixed-signal ICs tailored for automotive powertrain and engine control. It complements microcontrollers like the KEA and S32K series by providing the necessary interface and driving capabilities for external loads. The MC33880 series is specifically optimized for cost-effective, high-reliability solutions in evolving automotive quality standards, serving as a critical link between digital control logic and physical actuation.

Replacement Considerations
