Quick Start
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  Oscilloscope  Two voltmeters  Two ammeters  Lab cables with appropriate current rating  USB Micro-B cable  PC with Windows 7 or newer operating system and USB port

Setup Overview
A typical bench setup for the MAX77960/MAX77961 EV Kit is shown in Figure 2.
Procedure
The EV kit is fully assembled and tested. Follow the steps below to install the EV kit software, make required hardware 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 configured 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.
Note: Do not turn on the DC power supply until all connections are made.
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.
2) Install the EV kit software on your computer by running 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 Framework 4.5 or later. If you are connected to the Internet, Windows automatically updates the .NET framework as needed.

3) The EV kit software launches automatically after installation, or alternatively, it can be launched by clicking on the icon in the Windows Start menu.
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.

5) Use the USB cable provided with the EV kit to connect the EV kit to the PC's USB port.
6) Connect a 2- or 3-cell Li-ion battery or simulated battery to the connectors labeled BATTP and BATTN.
7) Connect a DC power supply to the connectors labeled DCIN and GND.
8) Launch the MAX77960/MAX77961 GUI software.
9) Select Device > Connect from the window options to connect to the EV kit.

Detailed Description of Software
The MAX77960/MAX77961 GUI software provides an easyto-use interface to control the function blocks of the IC.
Software Installation
Double-click the MAX77960_MAX77961GUISetupX.X.X.exe icon to begin the installation process. Follow the prompts to complete the installation. The evaluation 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 communication. An example of a successful connection is shown in Figure 4.

Register Write Access
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.
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.

Detailed Description of Hardware
Battery Charger Test Setup
1) Connect a 2- or 3-cell Li-Ion battery or simulated battery 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.
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.
7) In the Configuration 0-3 tab, set Fast Charge Current 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

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.
10) Use data log equipment to log the charge current and battery voltage profile while charging a 2- or 3-cell Li-ion battery.
