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. 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 LOW-SIDE DRIVER DH SUFFIX VW SUFFIX (PB-FREE) 98ASH70702A 20-PIN HSOP ORDERING INFORMATION Device MC33385DH/R2 MC33385VW/R2 Temperature Range (TA) -40°C to 125°C Package 20 HSOP VPWR Voltage Regulator VCC 33385 OUT1 OUT2 OUT3 OUT4 GND1-4 MCU NCS CLK SDI SDO NRE NON1 NON2 NON3 NON4 Figure 1.
