2.4 Interfaces

The HSS-HCMOTHERBRDEVM has several different power, programming, and diagnostic interfaces available.

The power interfaces are summarized below.

Table 2-3 Power Interfaces
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.

Table 2-4 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.
