Notes
1.This parameter is guaranteed by design but is not production tested.
2.ESD testing is performed in accordance with the Human Body Model (HBM) (Per AEC-Q100-002, CZAP = 100pF, RZAP = 1500) and the Machine Model (MM) (Per AEC-Q100-002, CZAP = 200pF, RZAP = 0). ESD data available upon request.
3.All pins when tested individually.
4.Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause malfunction or permanent damage to the device.
5.Freescale's Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow Temperature and Moisture Sensitivity Levels (MSL), Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e. MC33xxxD enter 33xxx), and review parametrics.




Description

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 33811 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.

33811 features, along with cost effective packaging, make the 33811 ideal for powertrain solenoid monitoring applications.
