MC10XSC425EK

Overview

The MC10XSC425EK is a high-side switch integrated circuit manufactured by Freescale Semiconductor. It features four low RDS(ON) MOSFETs, specifically configured as dual 10 mΩ and dual 25 mΩ switches at 25 °C. The device operates within a voltage range of 6.0 to 20 V, with an extended mode supporting 4.0 to 28 V. It includes an 8.0 MHz 16-bit SPI interface for control and status reporting with daisy chain capability. Protection features include smart overcurrent shutdown, severe short-circuit detection, overtemperature protection with time-limited autoretry, and fail-safe mode. Output diagnostics support open-load detection compliant with bulbs or LEDs and short-to-battery detection.
