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.
