MC06XS4200

Overview

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 R

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.
