1.4 Specification

The HSS-HCMOTHERBRDEVM and daughtercard boards are meant to be used together to evaluate automotive applications where Smart eFuse high-side switches are used to drive primarily off-board loads. This EVM contains a pre-flashed microcontroller with firmware that acts as a SPI<-> USB bridge between the Smart eFuse high-side switch (SPI) and the host PC system running the GUI (USB). The EVM is designed for ease-of-use and all that is needed is to plug in USB and relevant loads, supply power, and evaluate through the GUI. A block diagram of the various blocks of the EVM can be seen below.

As seen from the image above, the EVM has multiple power rails that are derived from input power sources. The 12V/48V supply voltage is fed into a TPSM5601R5 buck converter to derive the 3.3V/5V rail for the high-side switch. A TLV767 LDO is used to derive the 3.3V microcontroller supply from the 5V USB connection through the PC.

Note that this board is intended to evaluate the standard functionality of the device. The board is not designed to withstand automotive transients events such as hard short-to-ground events, reverse battery events, and ISO 16750-2 load dumps. If short-to-ground is to be performed on the EVM, please refer to the Transient Testing section on how to run transient testing safely on the EVM.
