            MC33291L : 1.4 Ohm Rdson Eight Output Switch with SPI
            The MC33291L is an eight output low side power switch with 8 bit 
            serial input control. The MC33291L is a versatile circuit designed 
            for automotive applications, but is well suited for other 
            environments. The MC33291L incorporates SMARTMOS technology, with 
            CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. 
            The MC33291L interfaces directly with a microcontroller to control 
            various inductive or incandescent loads. 
  
            MC33291L Features
            Designed to Operate Over Wide Supply Voltages of 5.5 to 26.5 V 
            Interfaces Directly with Microprocessor Using 8 Bit SPI I/O 
            Protocol to 3.0 MHz 
            Outputs Current Limited to 1.0 to 3.0 A for Switching 
            Incandescent Loads 
            Output Voltages Clamped to 53 V During Inductive Switching 
            Open Load Detection (Outputs OFF) 
            Overvoltage Detection and Shutdown 
            Outputs have Independent Over Temperature Detection and Shutdown 
            Output Mode Programmable for Sustained Current Limit or 
            Shutdown
