MC22XS4200BEKR2

电源开关 IC - 配电 24V Dual 22mOhms SOICW-EP 32 Rail

Dual 24 V, 22 mOhm high-side switch

The MC22XS4200BEKR2  22XS4200 device is part of a 24 V dual high-side switch product family with

integrated control, and a high number of protective and diagnostic functions. It

is designed for truck and bus applications. The low RDS(on) channels (<22 mΩ)

can control different load types; bulbs, solenoids, or DC motors. Control, device

configuration, and diagnostics are performed through a 16-bit serial peripheral

interface (SPI), allowing easy integration into existing applications. This device

is powered by SMARTMOS technology.

Features  MC22XS4200BEKR2

• 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 (channel in OFF and ON state), also 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  MC22XS4200BEKR2

• Truck, bus and 24 V transportation systems

• Resistive, capacitive, and inductive loads
