MC20XS4200BFK

Dual 24 V, 20 mOhm high-side switch

The 20XS4200 MC20XS4200BFK 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.

Features MC20XS4200BFK

• Two fully-protected 20 mΩ (@ 25 °C) high-side switches

• Up to 4.4 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

• Openload detection (channel in OFF and ON state), also for LED applications (7.0 mA typ.)

• Normal operating range: 8.0 to 36 V, extended range: 6.0 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

Definition MC20XS4200BFK

This pin either outputs a current proportional to the channel’s output current or a

voltage proportional to the temperature of the GND pin (pin 14). Selection between

current and temperature sensing, as well as setting the current sensing sensitivity

are performed through the SPI interface. An external pull-down resistor must be

connected between CSNS and GND.
