Freescale AN2467 Dual 10 m high-side switch Datasheet

Analog, Mixed-Signal and Power Management
MC10XSD200
Dual 10 mΩ high-side switch
Target Applications
Overview
• Industrial (12 V and 24 V systems)
The MC10XSD200 device is part of a 36 V high-side switch product family with
• Halogen bulbs
integrated control and a high number of protective and diagnostic functions. It is
• Light-emitting diodes (LEDs)
designed for industrial applications. The low RDS(on) channels (< 10 mΩ) can control
• Low-voltage industrial lighting
different load types, including bulb lamps, solenoids or DC motors.
• 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.

Analog Solutions
Accurate temperature and current sensing
Offers a 16-bit SPI interface for daisy chaining multiple
devices
Open load detection (channel in, off and on states) and
LED applications (7.0 mA typical)
Allows multiple channel and device current sensing with
only one precision resistor
current of each channel can be sensed with
a programmable sensing ratio. Whenever
communication with the external MCU is
lost, the device enters a fail-safe operation
mode, but remains operational, controllable
