Detailed Description

of Hardware

The MAX8731A includes all of the functions necessary

to charge a smart battery. The EV kit is capable of

charging with a maximum current of 8.064A and a max-

imum voltage of 19.2V. For more information on the

operation of the MAX8731A, refer to the Detailed

Description section of the MAX8731A IC data sheet.

Connecting a Smart Battery

The MAX8731A EV kit is capable of charging two smart

batteries consecutively. Before connecting a battery, turn

off power to the EV kit. To use charger A, set jumper JU1

to position 1-2 and connect the battery to BATT+_A,

BATT-_A, THM_A, SCL, and SDA. To use charger B, set

jumper JU1 to position 2-3 and connect the battery to

BATT+_B, BATT-_B, THM_B, SCL, and SDA.

Evaluating the MAX8731A Above 25V

To evaluate the MAX8731A with an input voltage

greater than 25V (up to 28V), capacitors C1, C11, C13,

and C20 must be replaced with higher voltage-rating

parts.
