MAX8903A Evaluation Kit

vluates:–E/MAX8903Y

General Description

Features

The MAX8903A evaluation kit (EV kit) is a fully assem-

bled and tested circuit board for evaluating the 2A, 1-cell

Li+ DC-DC battery charger. The EV kit charges a sin-

gle-cell lithium-ion (Li+) battery from a DC input (AC

adaptor) or a USB 100mA/500mA source and provides

system power from the DC input, USB input, or battery.

Battery charge current and SYS current limit are inde-

pendently set. Charge current and DC converter output

current limit can be set up to 2A, respectively. The USB

input current can be set to 100mA or 500mA and USB

suspend mode is also supported. Power not used by

the system is available to charge the battery.

♦ DC-DC Converter Output Current-Limit

Adjustment Range of 0.5A to 2A (EV Kit Standard

Configuration: 2A)

♦ Battery Charger Current-Limit Adjustment Range

of 0.5A to 2A (EV Kit Standard Configuration: 1A)

♦ USB Current Limit of 100mA or 500mA

♦ Efficient 4MHz Switching DC-DC Converter

Powers System Load and Charger

♦ Instant On—Works with No Battery or Low

Battery

The EV kit comes standard with the MAX8903A

installed. However, the EV kit can also be used to evalu-

ate the MAX8903B–MAX8903E and MAX8903Y by

replacing the MAX8903A (U1) with the preferred IC.

♦ 28-Pin, 4mm x 4mm Thin QFN Package with

Exposed Pad

♦ Fully Assembled and Tested
