MC35XS3500HFKR2

Overview

The MC35XS3500HFKR2 is a smart high-side switch designed for automotive and industrial lighting. It integrates five low Rds(on) MOSFETs, each with a resistance of 35 mΩ, to control separate resistive loads. The device utilizes a 16-bit SPI interface operating at 3.3 V or 5.0 V for programming, control, and diagnostics. Each output features independent pulse-width modulation (PWM) control via the SPI interface. The component includes sophisticated failure mode handling, multiphase control, and output edge shaping to enhance electromagnetic compatibility. It is housed in a 24-pin power-enhanced 12 x 12 mm non-leaded PQFN package with exposed tabs.
