MC33982BPNA

Overview

The MC33982BPNA is a high-side power switch integrated circuit manufactured by NXP USA Inc., designed for automotive applications. It features a single N-channel output with an SPI interface for control and diagnostics. The device operates within a load voltage range of 6V to 27V and requires a supply voltage (Vcc/Vdd) between 4.5V and 5.5V. Key electrical specifications include a typical on-resistance of 2 milliohms and a junction operating temperature range from -40°C to 150°C. The component is housed in a 16-PowerQFN package measuring 12x12 mm.

Feature Summary

• Integrated controlled slew rate functionality to minimize electromagnetic interference during switching events.
• Built-in watchdog timer ensures system reliability and fault recovery capabilities.
• Comprehensive fault protection including fixed current limiting, open-load detection, over-temperature shutdown, and over-voltage protection.

Applications

• Motorcycle Engine Control Unit (ECU)
• Small Engine Control Systems
• Scooter and Three-wheeler Management
• Lawn Equipment Controllers
• Electric Generators

Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm that the 16-PQFN package dimensions match the design requirements. Ensure compatibility with existing SPI communication protocols and voltage levels. Check for RoHS compliance status if required by specific regional regulations, noting the provided data indicates non-compliance. Validate thermal management solutions given the 150°C junction temperature rating.

Selection Notes

Select this component for high-side switching applications requiring precise diagnostic feedback via SPI. The low on-resistance supports efficient power delivery for small engine loads. Consider the integrated fault protections for robust system safety. Evaluate the 16-PowerQFN package for space-constrained PCB layouts. Ensure the controller can handle the specified 6V to 27V load voltage range typical of automotive systems.
