Test Procedure
1) Do not turn on the DC power supplies until all con-
nections are made.
The EV kit is fully assembled and tested. Use the follow-
ing steps to verify board operation.
2) Confirm all jumpers are at their default positions as

SINK Mode
When the MAX77958 is configured as the SINK, the
MAX77958 enables the charger mode of the MAX77962
and set the input current limit of the MAX77962 according
to the USB Type-C and BC1.2 detection result.
indicated in Table 2.
3) Connect a Micro-B USB cable from the computer’s
USB port to the MAX77958 EV kit.
4) Connect the DC power supply to the loop labeled
SYS and GND.
5) Adjust the DC power supply to 7V and turn it on.
1) Connect the battery simulator between BATTP and
BATTN, adjust the voltage to 7V and turn it on.
6) Follow the description of software covered in page
7 to install the MAX77958EVKIT-2S3.EXE software
program.
2) Connect USB Type-C AC adapter into the EV kit.
3) Observe the current reading from the battery simu-
lator, the default fast charging current should be
450mA.
7) Open the MAX77958 GUI and go to the Device
drop-down menu, and press the Connect button in
the drop-down list.
SOURCE Mode
When the MAX77958 is configured as the SOURCE, the
MAX77962 automatically switches to reverse-buck mode,

1) Connect USB Type-C adapter into the EV kit and see
whether the MAX77958 detects SINK and configures
input current limit correctly.
2) Make sure no USB Type-C cable is connected.

Detailed Description of Firmware
The firmware of the MAX77958 consists of two main
parts: the core firmware and customization script.
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 application system, giving more flexibility for
system design. It is based on the customization script
update, which can achieve functions such as GPIO
matrix control, charger configuration initialization, etc.
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.
