5) Make connections to the EV kit board following guid-
ance as shown in Figure 1. The two main inputs to
apply are the battery and the charging adaptor. For
quick start evaluation, it is suggested to use a 5V
power supply at the CHGIN input and a battery volt-
age greater than 3.6V at the BATT input. The optional
voltmeter and ammeter location for testing charger ef-
ficiency is indicated in Figure 1. When set up properly
with both CHGIN = 5V and BATT = 3.8V input, the
SYS voltage is regulated above VBATT by default.

Procedure
The EV kits are fully assembled and tested. Follow the
steps below to install the EV kit software, make required
hardware connections, and start operation of the kits. The
EV kit software can be run without attached hardware. Note
that after communication is established, the IC must still be
configured correctly for the desired operation mode. Make
sure the PC is connected to the internet throughout the pro-
cess so that the USB driver can be automatically installed.
6) Connect the EV kit to a USB port on the PC using a
USB Micro-B cable.
7) Open the GUI software, click Device > Connect. A
window pops up showing that a slave address corre-
spondingtoMAX77975/MAX77976and/orMAX77958
has been found. If not, check the connection.
1) Visit www.maximintegrated.com/products/MAX77975_
MAX77976 under the Design Resources tab to down-
load the latest version of the MAX77975/MAX77976
EV kit GUI software. Save the software to a tempo-
8) Start evaluating the part with the GUI software.
Unlock the write protection and adjust the char-
ger mode, the charging input current limit, and the
charging current to start evaluating the basic charger
features as described in the Configurations 0-13
Tabs section. Play with the charger mode and other
register settings to evaluate the smart power path and
more features. Remove the CHGIN input and use the
real travel adaptor to evaluate charging the battery
through the USB Type-C port.

program inside the temporary folder. The program
files are copied, and icons are created in the Windows
Start menu. The software requires the .NET Frame-

on-screen instructions to complete the installation.
Before configuring at any tab, click Read Once to make
sure all the displayed configurations are in sync with
the IC configuration state. Alternatively, click Start Auto
Read and set corresponding read frequency to keep this
page up to date at all times. Follow the guidance on the
MAX77975/MAX77976 IC data sheet for the detailed

of Configuration 6 to Unlock 0x3 state, then click the
Write button. Click Read to make sure the change is
in place. After the unlock, all configuration registers can
be configured. To get started charging a battery with the
desired current setting, set Chgin Input Current Limit
in Configuration 9, then set Fast Charging Current in
Configuration 2, then set Mode = 5 in Configuration 0 to
switch from buck-only mode to charging mode.
USB Power Delivery Test
1) Source capability request function test.
2) Connect USB power delivery AC adapter to the EV

command over the CC pin to the TA, and the TA pro-
vides a list of available source capabilities.
5) Review the source capabilities and make a note of the
desired PDO.

Detailed Description of Firmware for
MAX77958
The firmware of MAX77958 consists of two main parts:
the core firmware and customization script.
2) Connect 3.8V to BATT, do not disconnect the EV kit from
the PC during the customization script block update.
3) Click on Tools in the menu bar and then go to CUS
Command Block Update.
The core firmware is compliant with the USB Type-C
1.3 and PD 3.0 specifications. The customization script
is based on the application system, giving more flex-
ibility for system design. It is based on the customiza-
tion script update, which can achieve functions such as
GPIO matrix control, charger configuration initialization,
etc. Future USB Type-C and PD specification changes
can be accommodated by updating the MAX77958 core
firmware. See the Core Firmware Update section of this
data sheet.
4) Click on the Open button in the pop-up window to
load the latest customization script, and then click on
Start to activate the customization script update.
5) Figure 11 shows the customization script update pro-
cess complete.
Core Firmware Update
1) Follow the initial test setup to connect the GUI with
the MAX77975/MAX77976 EV kit.
See the MAX77958 Customization Script Block Update
section and the MAX77958 Customization Script and
OPCode Command Guide for details about the custom-
ization script.
2) Connect 3.8V to BATT and do not disconnect the EV
kit from the PC during the firmware update.
3) Click on Tools in the menu bar and then go to
Firmware Update.
MAX77958 Customization Script Block Update
4) Click on the Open button in the pop-up window to
load the latest firmware. In the file select window, click
on the .bin file, and then select Start to activate the
firmware update.
The customization script defines the application-specific
behavior of the MAX77958. An example is setting the
input current limit of the charger when USB device detec-
tion is completed.
