MC33882PEKR2

Overview

The MC33882PEKR2 is a six-output low-side power switch manufactured by NXP USA Inc., designed for automotive and industrial applications. It features an N-channel output configuration with a load voltage range of 8V to 25V and a supply voltage of 4.5V to 5.5V. The device offers a typical on-resistance of 400 milliohms per channel and supports SPI and parallel input interfaces. Packaged in a 30-BSOP (HSOP) format, it includes fault protection mechanisms such as fixed current limiting, open-load detection, and overvoltage protection, operating within a junction temperature range of -40°C to 150°C.

Feature Summary

• Supports dual control via Serial Peripheral Interface (SPI) and parallel inputs for flexible system integration.
• Integrates comprehensive diagnostic capabilities including open-load detection and fault status reporting.
• Features internal dynamic clamping and current limiting to protect against inductive load switching transients.

Applications

• Automotive engine control units (ECU) for managing inductive and incandescent loads
• Small engine control systems requiring robust low-side switching
• Industrial motor control and driver circuits

Procurement Notes

Verify the specific suffix 'R2' indicates tape-and-reel packaging versus standard tube formats when sourcing. Confirm RoHS compliance status and lead times due to potential lifecycle changes. Ensure interface compatibility with existing microcontroller SPI configurations before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring multiple independent low-side switches with integrated diagnostics. The dual control interface allows for redundancy in critical safety applications. Evaluate thermal management requirements given the 400 milliohm resistance and potential current loads in dense PCB layouts.

Part Context

This part belongs to the MC33882 family of smart low-side switches from NXP Semiconductors.
