DESCRIPTION

· The 22XS4200 is a dual 24 V, 22 mΩ high-side switch designed for truck and bus applications.

· It features integrated control and a comprehensive set of protective and diagnostic functions.

· The device supports control of various load types, including bulbs, solenoids, and DC motors, via a 16-bit SPI interface.

· Powered by SMARTMOS technology, it offers programmable output voltage slew rates and dynamic overcurrent threshold profiles.

FEATURES

· Two fully-protected 22 mΩ (at 25 °C) high-side switches.

· Up to 4.2 A steady state current per channel.

· Separate bulb and DC motor latched overcurrent handling.

· Individually programmable internal/external PWM clock signals.

· Overcurrent, short-circuit, and overtemperature protection with programmable autoretry functions.

· Accurate temperature and current sensing.

· Open load detection in both OFF and ON states, suitable for LED applications (7.0 mA typ.).

· Normal operating range: 8.0 V to 36 V, extended range: 6.0 V to 58 V.

· 3.3 V and 5.0 V compatible 16-bit SPI port for device control, configuration, and diagnostics at rates up to 8.0 MHz.

APPLICATIONS

· Truck, bus, and 24 V transportation systems.

· Resistive, capacitive, and inductive loads.
