MC33882PEPR2

Overview

The MC33882PEPR2 is a smart six-output low-side switch designed for automotive applications. It integrates open-drain power MOSFETs with internal dynamic clamping and current limiting to control inductive and incandescent loads up to 1.0 A per output. The device supports dual input control via Serial Peripheral Interface (SPI) and parallel inputs, enabling fault-tolerant system designs. Key electrical characteristics include an on-resistance of 0.4 Ω at 25°C and 13 V supply voltage, SPI operation guaranteed up to 2.0 MHz, and load dump robustness rated at 60 V transient on the power supply pins.

Feature Summary

• Dual-mode control interface supporting both serial peripheral interface communication and direct parallel input logic for flexible system integration.
• Integrated protection mechanisms including internal dynamic clamping, fixed current limiting, and overvoltage shutdown to safeguard connected loads.
• Diagnostic capabilities providing detailed fault status reporting and output-specific monitoring for enhanced system reliability.

Applications

• Automotive engine control units managing fuel injectors and ignition coils
• Small engine control systems requiring reliable load switching
• General automotive lighting and accessory control modules

Procurement Notes

Verify the specific suffix PEPR2 against official NXP documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints and reflow profiles. Confirm RoHS compliance status and check for any active product lifecycle notices or last-time buy dates before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring multiple low-side switches with integrated diagnostics and high surge tolerance. The dual control interface offers redundancy for safety-critical applications. Consider the thermal performance of the HSOP-30 package and ensure adequate heat dissipation for continuous high-current operation under maximum ambient temperature conditions.

Part Context

The MC33882 belongs to NXP's portfolio of smart power switches tailored for automotive engine management. It replaces discrete transistor solutions by integrating control logic, drivers, and protection circuits into a single IC. This integration reduces board space and improves reliability in harsh automotive environments compared to standard MOSFET arrays.

Replacement Considerations

Check for updated revision numbers within the MC33882 family. Verify pin-to-pin compatibility if substituting with other variants such as MC33882VW or MC33882PVWR2, ensuring functional equivalence in control interfaces and electrical ratings.

FAQ
