Advance Information  
Solenoid Monitor Integrated  
Circuit (IC)  
33811  
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.  
SOLENOID MONITOR  
These features, along with cost effective packaging, make the  
33811 ideal for powertrain solenoid monitoring applications.
