Procedure  
The EV kit is fully assembled and tested. Follow the steps  
below to install the EV kit software, make required hard-  
ware connections, and start operation of the kit. The EV kit  
software can be run without hardware attached. Note that  
after communication is established the IC must still be con-  
figured correctly for desired operation mode. Make sure the  
PC is connected to the internet throughout the process so  
that the USB driver can be automatically installed.

Quick Start  
1) Visit www.maximintegrated.com/products/MAX77960  
or www.maximintegrated.com/products/MAX77961  
under the Design Resources tab to download the  
latest version of the MAX77960/MAX77961 EV kit  
GUI software. Save the software to a temporary folder  
and unpack the zip file.  
Required Equipment  
MAX77960/MAX77961 EV kit  
Adjustable DC power supply  
Battery or simulated battery  
• 2- or 3-cell Li-ion protected battery  
• Simulated battery or preloaded power supply  
2) Install the EV kit software on your computer by run-  
ning the MAX77960_MAX77961GUISetupX.X.X.exe  
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-  
work 4.5 or later. If you are connected to the Internet,  
Windows automatically updates the .NET framework  
as needed.

tery to the connectors labeled BATTP and BATTN.  
4) Make jumper connections based on the Default  
Position column in Table 1. Change it later when  
evaluating more features. If evaluation is with a 3-cell  
Li-ion battery or equivalent simulated battery, place J8  
in 2-3 position so that the MAX77960/MAX77961 are  
configured for 3-cell.  
7) Connect a DC power supply to the connectors labeled  
DCIN and GND.

Detailed Description of Software  
The MAX77960/MAX77961 GUI software provides an easy-  
to-use interface to control the function blocks of the IC.  
Software Installation  
Double-click the MAX77960_MAX77961GUISetup-  
X.X.X.exe icon to begin the installation process. Follow  
the prompts to complete the installation. The evalua-  
tion software can be uninstalled in the Add/Remove  
Programs tool in the Control Panel. After the installation  
is complete, open the Maxim Integrated/MAX77960_  
MAX77961 folder and run MAX77960_MAX77961.exe  
or select it from the program menu. Figure 3 shows a  
splash screen containing information about the evaluation  
kit that appears while the program is loading.  
Establish Communication  
Power up the MAX77960/MAX77961 by connecting a  
2- or 3-cell Li-ion battery or simulated battery at BATTP/  
BATTN. Open the GUI software and select Device >  
Connect. A window should pop up showing that a slave  
address 0xD2 has been found. If not, check the USB  
connection and power. Choose Read and Close and the  
status bar displays “Connected” to signify active commu-  
nication. An example of a successful connection is shown  
in Figure 4.

Register Write Access  
Detailed Description of Hardware  
Modification of the charger registers are locked by default  
to prevent arbitrary changes. Therefore, changes made to  
the charger registers in the locked state are not applied  
to the EV kit. To unlock register writing, select the 0x3 =  
Unlocked option in the Charger Settings Protection  
dropdown menu from the Charger Configurations 6  
register in the Configuration 4-7 tab, and then click Write  
(Figure 6). Read the register and the Charger Settings  
Protection setting should remain in the 0x3 = Unlocked  
state to signify open register access.  
Battery Charger Test Setup  
1) Connect a 2- or 3-cell Li-Ion battery or simulated bat-  
tery between BATTP and BATTN.  
2) Adjust voltage and current limits of the DC power  
supply to 5.0V and 3.0A. Output of the power supply  
is off.  
3) Connect the power supply between DCIN and GND  
on the EV kit board.  
4) Open the EV kit GUI and connect to the EV kit.  
From this point onwards, modifications written to any of  
the registers apply to the EV kit. For example, the CHGIN  
Input Current Limit can be changed in the Charger  
Configurations 8 register by selecting the required value  
and clicking Write (Figure 7), but only after the registers  
have been unlocked.  
5) In the Configuration 4-7 tab, set Charger Settings  
Protection in the Charger Configurations 6 register  
to 0x3 = Unlocked. Click Write to send the command  
to the charger.

6) Program the appropriate charger settings for your  
system. In the Configuration 8-10 tab, set CHGIN  
Input Current Limit in the Charger Configurations  
8 register. Press Write to send the command to the  
charger. Note that the maximum setting of CHGIN  
Input Current Limit for the MAX77960 is 0x40 =  
3150mA.  
MAX77960 is 0x21 = 3000mA.  
8) In the Charger Configuration 0 register of the  
Configuration 0-3 tab, set Smart Power Selector to  
0x5 = Charger = On, OTG = Off, and DCDC = On  
and click Write to enable charger mode.  
9) Turn on the DC power supply’s output to enable  
charging.  
7) In the Configuration 0-3 tab, set Fast Charge Cur-  
rent in the Charger Configurations 2 register. Press  
Write to send the command to the charger. Note that  
the maximum setting of Fast Charge Current for the  
10) Use data log equipment to log the charge current and  
battery voltage profile while charging a 2- or 3-cell  
Li-ion battery.
