MC06XS4200
Dual 24 V, 6.0 mOhm High Side Switch
Overview
Applications
The MC06XS4200 device is part of a 24 V high side switch product family with integrated
control, and a high number of protective and diagnostic functions. It is designed for truck,
bus, and industrial applications. The low RDS(ON) channels (<6.0 mΩ) can control different
load types; bulb lamps, 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. Both
channels can be controlled individually by external or internal clock signals, or by direct
inputs. Using the internal clock allows fully autonomous device operation. Programmable
output voltage slew-rates (individually programmable) help improve electromagnetic
compatibility (EMC) performance.
To avoid shutting off the device due to inrush current, while still being able to closely
track the load current, a dynamic over-current threshold profile is featured. Switching
current of each channel can be sensed with a programmable sensing ratio. Whenever
communication with the external microcontroller is lost, the device enters a Fail-safe
operation mode, but remains operational, controllable, and protected.

Questions
• Does your application require high lifetime expectancy (over 30,000 hrs) or 1.5 million km?
• Do you need to improve your application robustness with respect to wear out mechanisms?
• Do you have a need to drive higher nominal and transient voltages?
• Do you have a need to drive higher nominal load currents?
• Does your system require Fail-safe operation?
• Do you need pulse-width modulation (PWM) for load protection/control and efficiency?
• Do you need a device that can report Diagnostics (opens, shorts, over current, over temperature,
etc.)?
• Do you have a need to reduce cost, size, weight and improve efficiency?
