MC15XS3400CPNA

Overview

The MC15XS3400CPNA is a quad high-side switch designed for low-voltage automotive lighting applications. It features four N-channel MOSFETs with a typical RDS(on) of 35 mOhm, capable of controlling separate loads such as 28 W bulbs or LEDs. The device operates within a temperature range of -40 °C to 125 °C and utilizes a 16-bit SPI interface for programming, control, and diagnostics. It supports selectable slew rates and includes built-in protections against transient, over-current, over-voltage, thermal, and under-voltage conditions.

Feature Summary

• Integrates four low-resistance N-channel MOSFETs for independent load control
• Utilizes a 16-bit serial peripheral interface (SPI) for configuration and diagnostics
• Includes comprehensive protection mechanisms against electrical and thermal faults
• Supports programmable fault current trip levels and lamp inrush duration

Applications

• Low-voltage automotive lighting systems
• Control of incandescent bulbs in vehicle exterior or interior lighting
• LED lighting module driving in automotive environments
• High-side switching applications requiring diagnostic feedback

Procurement Notes

Verify the specific suffix CPNA corresponds to the required package and tape-and-reel configuration. Confirm RoHS compliance status matches project requirements. Ensure the supplier provides valid traceability documentation for automotive-grade components. Check for any obsolescence notices from NXP Semiconductors before finalizing procurement plans.

Selection Notes
