Overview

www.DataSheet4U.com Freescale Semiconductor Technical Data Document Number: MC33385 Rev.

6.0, 11/2006 Quad Low-side Driver The MC33385 is a Quad Low-side Driver fully protected switch.

This device is a general purpose Low-side Driver but has been especially designed to operate in engine management applications as injector driver or automotive gear box.

It is interfaced directly with a microcontroller for parallel control of the load and the individual output diagnostic is done through a SPI.

The diagnostic logic recognizes 4 failure types at each output stage: overcurrent, short to GND, open load, and over-temperature.

Key Features

  • RDSON of 250mΩ per Output at 25°C.
  • Supplied from the main 5V VCC.
  • Input CMOS Compatible.
  • Diagnostic through SPI.
  • Nominal Current of 2A per Output.
  • Current Limitation at 3A with Automatic Turn Off.
  • Output Internally Clamped at 50V typ for Inductive Load Drive.
  • Junction to Case Thermal Resistance of 4.4°C/W.
  • Individual Output over Temperature Shutdown.
  • Pb-Free Packaging Designated by Suffix Code VW 33385 LO.
