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. •Temperature Range from -40 °C to +125°C •PWM Capability •Power TMOS # 1 Over-Current and Short-Circuit Protection •Voltage Range 7V to 40V •Extended Temperature Range from -40 °C to 125°C •Load Dump Protected •Over Voltage Detection and Activation of OUT2 during Overvoltage •Single Input Control for both Output Stages •Capacitor Value of 100nF Connected to Pin CP •Analog Input Control Measurement Detection •OUT1 LOAD leakage measurement detection Freescale Semiconductor, Inc.
