MC33385 : Quad Low-Side Driver - 0.25 Ohm

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 application 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 the overcurrent, the short to GND, the openload and the over-temperature.

MC33385 Features

• RDSON of 250mW per Output at 25 deg 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 deg C/W
• Individual Output over Temperature Shutdown
