MC33882EP

Overview

The MC33882EP is a smart six-output low-side switch designed for automotive engine control applications. It integrates open-drain power MOSFETs capable of controlling system loads up to 1.0 A per channel. The device supports dual input control via Serial Peripheral Interface (SPI) and parallel inputs, facilitating fault-tolerant system designs. Key electrical characteristics include an on-resistance of 0.4 Ω at 13 V supply voltage and SPI operation guaranteed up to 2.0 MHz. It features internal dynamic clamping, current limiting, and a 52 V clamp on each output to protect against inductive load switching transients.

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, current limiting, and output-specific diagnostics with fault status reporting.
• Robust transient handling capability with load dump robustness rated at 60 V transient on the power supply pins.

Applications

• Automotive engine control systems
• Fault-tolerant load switching applications
• Inductive and incandescent load control

Procurement Notes

Verify the specific suffix designation to ensure compatibility with required packaging and temperature grades. Confirm that the selected variant meets the necessary automotive qualification standards for the intended application environment. Cross-reference the ordering information with official NXP documentation to validate pinout and functional specifications before procurement.

Selection Notes

Select this component when a multi-channel low-side switch with integrated diagnostics is required for automotive environments. The dual control interface allows for redundancy and simplified wiring compared to pure SPI devices. Ensure the design accounts for the thermal dissipation requirements associated with the specified on-resistance under maximum load conditions.
