MC35XS3400CHFK

Overview

The MC35XS3400CHFK is a quad high-side switch IC designed for low-voltage automotive lighting applications. It integrates four N-channel MOSFETs with a typical on-resistance of 35 mOhm, capable of controlling separate loads such as 28 W bulbs or LEDs. The device features a 16-bit SPI interface for programming, control, and diagnostics. Key electrical parameters include a supply voltage range of 6 V to 20 V, an operating temperature range of -40 °C to 150 °C, and a maximum output current of 6 A per channel. It utilizes a 24-pin PowerQFN package measuring 12 x 12 mm.

Feature Summary

Integrates four low Rds(on) N-channel MOSFETs for independent load control
Utilizes a 16-bit SPI interface for comprehensive programming and diagnostics
Includes built-in protection against overcurrent, overvoltage, undervoltage, and thermal faults

Applications

Low-voltage automotive lighting systems
Control of incandescent bulbs and LED modules
Peripheral driver circuits in automotive environments

Procurement Notes

Verify the specific suffix CHFK against official NXP documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements prior to assembly. Ensure compatibility with existing SPI controller interfaces and validate that the 24-PowerQFN footprint matches the design layout. Check for any obsolescence notices or recommended replacement parts from the manufacturer.

Selection Notes

Select this component for applications requiring precise control of multiple high-current automotive loads via a serial interface. The integrated fault protection and diagnostic capabilities simplify system design by reducing external component count. Consider the 35 mOhm on-resistance for efficiency calculations and ensure the thermal management strategy supports the 150 °C junction temperature rating under expected load conditions.

Part Context

The MC35XS3400 belongs to the 35XS family of devices developed for automotive power distribution. Originally associated with Freescale Semiconductor, which was acquired by NXP, these components are engineered for robust performance in harsh automotive environments. The series provides scalable solutions for lighting and peripheral drivers, combining high current handling with sophisticated digital control features.
