The HSS-HCMOTHERBRDEVM has several different power, programming, and diagnostic interfaces available.
The power interfaces are summarized below.
Identifier | Name | Description |
---|---|---|
J8 | External VDD | Used for supplying external VDD to the high-side switch. See Transient Testing for more information. |
J9 | VBB | Main power source of the device. This is generally modeled from a 12 V automotive supply. |
J4, J6 | VOUT1 and VOUT2 | Channel outputs that go to the desired loading conditions. |
J5, J7 | GND | Ground connections. |
The motherboard EVM also has the following digital interfaces.
Identifier | Description |
---|---|
J12 | USB connection to host that is used to communicate with the Smart Fuse Configurator software. Note that the 3.3V power supply for the MCU is derived from USB via a 3.3V LDO. |
J13 | Used if an external SPI primary device wants to be used. In this scenario, connect the SPI primary device to the signals on this header and keep the USB port unplugged. |
J14 | JTAG used for programming the TM4C microcontroller. A source code package is provided, or the user can write their own MCU code from scratch. |
