MC06XS4200
Dual 24 V, 6.0 mOhm High Side Switch
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 RDS(ON) channels (<6.0 mΩ) can control different
load types; bulb lamps, solenoids, or DC motors.
Applications
• Automotive (12 V system)
• Truck, Bus, industrial vehicles (24 V
system)
Control, device configuration, and diagnostics are performed through a 16-bit serial
peripheral interface (SPI), allowing easy integration into existing applications. Both
• Low voltage automotive lighting
channels can be controlled individually by external or internal clock signals, or by direct • Halogen bulbs
inputs. Using the internal clock allows fully autonomous device operation. Programmable
output voltage slew-rates (individually programmable) help improve electromagnetic • Light-emitting diodes (LEDs)
compatibility (EMC) performance.
• Low and High beam
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
• Flashers
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
• Low voltage industrial lighting
operation mode, but remains operational, controllable, and protected.
