Quad Low-side Driver
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
The MC33385 is a Quad Low-side Driver fully protected switch. This
• RDSON of 250mΩ per Output at 25°C
• Supplied from the main 5V V
• 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
