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.
