MC08XS6421CEKR2 Description

Short technical summary and product information.

The MC08XS6421CEKR2 from NXP Semiconductors is a dual high-side switch designed for automotive lighting applications. It offers two channels with 8.0 mOhm resistance and two channels with 21 mOhm resistance, providing flexibility for various load types.

 

This device supports a wide operating voltage range from 7.08V to 18V, with an extended mode from 6.08V to 28V. It features a 16-bit, 5.0 MHz SPI interface for control and diagnostics, including overcurrent profiles, output monitoring, and fault reporting. Protection features include current limiting, open load detection, and thermal shutdown.

 

The MC08XS6421CEKR2 is available in a 54-SSOP exposed pad package, suitable for surface mounting. Its design facilitates ECU integration with compatible MCU software and PCB footprints within the 12XS6 family.

 

Key electrical characteristics include a sleep current below 5.0 µA and protection against -16V reverse polarity and ground disconnect. The switch type is general purpose with N-Channel output configuration.
