Dual 24 V, 6.0 mOhm High Side Switch

Freescale Semiconductor 

Features

• Two fully-protected 6.0 mΩ (@ 25 °C) high side switches

• Up to 9.0 A steady state current perchannel

• Separate bulb and DC motor latched over-current handling

• Fail-safe mode when microcontroller communication is lost

• Sleep mode with minimal supply current (< 10μA @ 24 V)

• Parallel output operating mode with improved switching synchronization

• Individually programmable internal/external PWM clock signals

• Over-current, short-circuit, and over-temperature protection with programmable autoretry

functions

• Accurate temperature and current sensing

• Open-load detection (channel in OFF & 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

Benefits

• Offer an intelligent high-side switch for 24 V truck and bus applications

• Allow decentralized lighting management (autonomous operation)

• Provide a high number of protective and diagnostic functions

• Allow to drive bulb lamps (Tungsten filament), LED lights and DC-motors

• Guarantee full functional and electrical compatibility between family members

• Offer a 16-bit SPI interface for daisy chaining multiple devices

• Allows multiple channel & device current sensing with only one precision resistor
