The MAX1926 evaluation kit (EV kit) is a complete, fully

assembled and tested, single-cell lithium-ion (Li+) bat-

tery charger. The EV kit provides a 4.2V output from

input as high as 12V, and delivers up to 1A charge cur-

rent. A light-emitting diode (LED) indicates the cell’s

charging status.

The EV kit can be also used to evaluate the MAX1925,

which is a single-cell Li+ battery charger with a 4.5V to

6.1V input voltage charge range.

DESCRIPTION

MAX1926 Evaluation Kit

o 5V to 12V Input Voltage Range

o Up to 1A Fast Charge Current

o LED Charge Status and Fault Indicator

o 12-Pin Thin QFN Package

o Surface-Mount Construction

o Fully Assembled and Tested

The MAX1926 EV kit is a fully assembled and tested

surface-mount board. Follow the steps below to verify

board operation. Do not turn on the power supply

until all connections are completed:

1) Verify that there is a no shunt across jumper JU1 (EN).

2) Connect a voltmeter across the EV kit’s BATT and

3) Connect a 5V to 12V power supply to the VIN pad.

4) Observe correct Li+ cell polarity. Connect the pos-

5) Turn on the power supply. The LED turns on if the

6) The LED turns off once the Li+ cell has been fully
