Freescale Semiconductor Advance Information Solenoid Monitor Integrated Circuit (IC) The 33811 is a 5 channel Solenoid Monitor IC that is used to verify proper electrical and mechanical solenoid operation. The IC contains five solenoid driver voltage monitoring stages and a serial peripheral interface (SPI) for fault communication and setup. The IC has the ability to determine the correct movement of solenoid armatures by analyzing the variation in the voltage profile, across the solenoid driver MOSFET, which represents the actual solenoid current profile. These features, along with cost effective packaging, make the 33811 ideal for powertrain solenoid monitoring applications. Features • Typical operating voltage range, 10.5 < VPWR < 15.5 volts • Interfaces to 3.3 and 5 volt microproce [ ... ]
