Evaluation Board Hardware Description
11.5 Power Terminal Connector
The Power Terminal Connector is a two position screw terminal that pr12 Volt and Ground
Terminals. The Ground terminal is marked “
GND ” and the +12 Volt Terminal is marked “ VBAT ”.
11.6 H-Bridge Terminal Connector
The H-Bridge Terminal Connector is a three position screw terminal that provides the following three
connections:
1.Output 1 of the H-Bridge - Pins 12, 13, 14, and 15 of the MC33926
2.Ground
3.Output 2 of the H-Bridge - Pins 27, 28, 29, and 30 of the MC33926
Terminal 1 of this terminal connector is labeled “ OUT1 ”
Terminal 2 of this terminal connector is labeled “ GND ”
Terminal 3 of this terminal connector is labeled “ OUT2 ”
11.7 MC33810 Output Terminal Connector
The MC33810 Terminal Connector is an eight position screw terminal. Four of the terminals are
connected to the VPWR line and the remaining four terminals are connected to the four injector driver
outputs of the MC33810 (see data sheet).
These terminals are marked as follows:
Terminal 1 of this terminal connector is labeled “ OUT0 ”
Terminal 2 of this terminal connector is labeled “ VPWR ”
Terminal 3 of this terminal connector is labeled “ OUT1 ”
Terminal 4 of this terminal connector is labeled “ VPWR ”
Terminal 5 of this terminal connector is labeled “ OUT2 ”
Terminal 6 of this terminal connector is labeled “ VPWR ”
Terminal 7 of this terminal connector is labeled “ OUT3 ”
Terminal 8 of this terminal connector is labeled “ VPWR ”
The terminals are arranged in this alternating fashion to allow the connection of loads to pairs of screw
terminals.
11.8 Controlling the MC33810 Outputs
The MC33810 Injector Driver Outputs OUT0 - OUT3 are controlled either by sending a “Driver ON/OFF
Command” SPI word or by toggling the Parallel, DIN0 - DIN3, input lines. In the MC33926 EVB the DIN0
- DIN3 lines are connected to the CNTL0 - CNTL3 parallel lines from the USB/SPI Dongle. Using SPIGen,
the CNTL0 - CNTL3 lines can be set high or low from the “Extra Pins” menu. To get to this menu, follow
