Hardware Description
The Block Diagram for the 33811 Evaluation Board is shown below:
Figure 1. 33811 EVB Block Diagram
The 33811 EVB consists of a 33811 Solenoid Monitor Circuit, a 33810 Injector/Ignition
Driver circuit, and a SPI and parallel interface.
Five outputs are provided, three injector outputs from the 33810 and two gate driver
outputs driving an IRF73410 dual MOSFET. The five outputs are monitored by the
33811 and fault messages are provided by the SPI interface. It is intended to be used
