5) Make connections to the EV kit board based on cell

pack configuration as shown in Figure 1. The cell

connects between the BAT- and BAT+ pads and the

charger/load connect between the PACK- and PACK+

pads. The load or charger circuit can be connected at

this time as well.

6) Connect the RJ-11 cable between the USB adapter

and the EV kit board. The GUI software establishes

communication automatically.

7) If the IC has not been configured, run the Configura-

tion Wizard in the EV kit software to configure op-

eration for the desired application circuit and lithium

cell type. Configuration information is permanently

saved inside the IC.

Detailed Description of Hardware

The MAX17201/MAX17211 EV kit boards provide a vari-

ety of features that highlight the functionality of the ICs.

The following sections detail the most important aspects

of the kit boards.

Communication Connections

The RJ-11 connector provides all signal lines necessary

for I2C, SMBus, 1-Wire, or 1-Wire overdrive communica-

tion between the IC and the software GUI interface. When

developing code separately, connections to the commu-

nication lines can be made directly to the board. Table 1

summarizes the connections that should be made. The

user must apply the appropriate external pullup resistors

to the communication lines when not using the DS91230+

communication interface.

External Thermistors

The MAX17201/MAX17211 can be configured to use up

to two external thermistors. All EV kit boards come with

these thermistors installed as surface mount components

RT1 and RT2. If the application requires direct thermal

contact to the cells, RT1 and RT2 can be removed and

replaced with leaded thermistors connected between the

RT1+/RT1- and RT2+/RT2- solder pads.
