Automotive Dual High Side TMOS Driver

The MC33285 is a dual high side TMOS driver designed for use in the harsh automotive switching applications.
The purpose of the MC33285 is to drive two power n-channel FETs in a high side application with an inductive load. The application in an automotive environment requires the capability of withstanding high voltages and load dump transients. The MC33285 is able to withstand reverse battery conditions at selected pins.
It protects the n-channel power FET on OUT1 under over current condition. This device has one input to control both stages on or off.
