1.1 Introduction

The HSS-HCMOTHERBRDEVM and accompanying daughter card EVMs (such as the HSS-2HCS10EVM) are hardware evaluation boards used for evaluation and development of Texas Instruments’ smart fuse high-side switch portfolio. A daughter card and motherboard approach is used in the hardware ecosystem to promote reuse of hardware and software, as well showcase the pin compatibility between different smart fuse devices.

As many of TI’s smart fuse high-side switches have a digital SPI interface, this hardware ecosystem is designed to simplify evaluation and development as well as reduce the need for the user to invest any significant software resources on the host side. The HSS-HCMOTHERBRDEVM has an integrated TM4C123 Cortex-M4F USB microcontroller that serves as a USB-to-SPI bridge between a host PC and the attached daughter card EVM. A simple Windows GUI program titled Smart Fuse Configurator is provided that allows a multitude of features including:

  • Reading/graphing load current, input/output voltage, and junction temperature via the high-side switch’s integrated ADC
  • Turn on/off channels and set operational settings such as PWM and current limit
  • Providing an interface to tune the I2T curve and compare with a customer wire profile for fuse replacement
  • Monitor device and channel fault status complete with aggregation statistics
  • Setup/configure all register settings of the high-side switch directly from the GUI
  • Direct register reads/writes through console view
  • Export/import settings as well as export development artifacts such as C configuration arrays/structures
  • Save high-side switch configuration data to MCU flash
  • Multi-lingual support including Japanese and English

The host GUI software is provided both in Windows binary and BSD-licensed source code. The host GUI does not require special drives, and uses standard Windows USB-HID calls to communicate with the HSS-HCMOTHERBRDEVM. Only Windows is supported with this EVM ecosystem. The EVM comes with the TM4C firmware pre-programmed without the need for the user to perform any initial firmware flashing.
