Smart Fuse Evaluation Module 1

1 Evaluation Module Overview

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

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.

1.2 Kit Contents

The EVM kit for the HSS-HCMOTHERBRDEVM includes the following:

• One HSS-HCMOTHERBRDEVM with MCU pre-flashed at factory with latest firmware

• One USB-C cable

The kit for the daughter cards are specific to the high-side switch associated with the daughter card. An example

kit contents for the HSS-2HCS10EVM daughter card can be seen below:

• One HSS-2HCS10EVM daughter card with a TPS2HCS10-Q1 high-side switch device

1.3 Specification

The HSS-HCMOTHERBRDEVM and daughter card boards are meant to be used together to evaluate

automotive applications where high-side switches are used to drive primarily off-board loads. This EVM contains

a pre-flashed microcontoller with firmware that acts as a SPI<-> USB bridge between the 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.

Figure 1-1. Block Diagram for HSS-HCMOTHERBRDEVM

As seen from the image above, the EVM has multiple power rails that are derived from input power sources. The

12 V supply voltage is fed into a LMR43610 buck converter to derive the 3.3V rail for the high-side switch. This

buck converter is used for the low IQ functionality, so that the low-power mode of the high-side switch can be

measured through the EVM. A TLV767 LDO is used to derive the 3.3V micocontroller supply from the 5 V 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, then TI recommends to add a

capacitance on the order of 220 µF so that the device can withstand the short-to-ground event. Additionally, as

the EVM is built for evaluation with ample test points, the EVM is not optimized for EMC testing and performance

including emissions, RF, and transient immunity tests.

3 Software

3.1 Software Usage

The Smart Fuse Configurator software is a companion software used to accompany the HSS-

HCMOTHERBRDEVM and corresponding daughter cards. This software can be downloaded from the product

page of the HSS-HCMOTHERBRDEVM and comes in the format of a packaged zip file. Simply unzip the

downloaded package and open the software on a Windows host machine. As the EVM uses USB-HID, there are

no drivers that are required to be installed and Windows automatically detects/installs the EVM without the need

to download proprietary software packages. The sections below describe the functionality of the Smart Fuse

Configurator in detail.

3.1.1 Command Center View

The Command Center View is meant to provide quick access to some of the common configuration and run-time

settings of the attached high-side switch. The user has the ability to turn on/off individual channels, plot/graph

ADC readings such as current sense, configure PWM settings, and put the device into several diagnostic states.

Note that by default, the device is set to auto-persist changes made in the GUI. This means that when the user

changes a setting on the interface, the command is sent through USB and translated as a SPI command to

persist to the high-side switch.

To enable/disable individual channels, simply click the desired channel in the Channel Enable box. This causes

the corresponding channel to turn on and conduct current if there is a load on the output. Likewise, to enable

current sense/graphing for a particular channel, click the desired channel on the Graph Settings box. This

causes the GUI to start a polling thread that periodically reads the high-side switch of the current sense register.

When a channel is enabled for graphing, the microcontroller automatically enables the relevant ADC bits in the

Figure 3-1. Current Sense Graph

Note that by default the device is set to collect and average a specified number of values before plotting them

on the graph. The maximum number of samples to collect can be changed through the Count setting and the

averaged number of samples can be changed with the Avg setting. In addition to load current, the device can

also be configured to graph/report FET temperature and output voltage. This setting is changed through the

Source box.

Figure 3-2. Voltage Graphing

The Quick Commands box provides various settings/diagnostic commands. The LPM exit current can quickly

be configured per-channel and the device can be forced into low-power mode through the Low-Power Mode

box. Once in low-power mode, if the load current on a corresponding channel exceeds what is configured in the

settings the device exits the low-power mode (or if the low-power mode box is unchecked). Refer to the device

data sheet (SLVSGY2) for exact operation behavior for low-power mode.

The Force Limp Home box forces the device to enter a limp home mode state. Generally, external circuitry is

designed to trigger the LHI pin of the high-side switch when a system-wide fault occurs, however for evaluation

purposes the Force Limp Home box causes the MCU to force trigger the LHI pin of the high-side switch. This

causes the device to default to the state configured in the device configuration registers of the high-side switch

(see the data sheet for details).

The Sleep Mode button prompts a dialog to put the device in sleep mode. In sleep mode, the device enters an

inactive state with minimal power consumption. In this mode, all device configurations are reset to their reset

values. The Smart Fuse Configurator software, however, has logic that restores the configured values after sleep

mode is exited. By clicking the sleep mode button, a prompt occurs to warn the user about the state change:
