33811 Solenoid Monitor

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.
