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 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.
