MAX1736 Evaluation Kit
General Description
The MAX1736 evaluation kit (EV kit) is a fully assembled
and tested circuit board containing a single-cell lithium-
ion (Li+) battery charger. The EV kit includes a current-
limited 800mA wall-cube AC adapter, which allows it to
safely and quickly charge an Li+ cell to +4.2V (+4.1V
with the MAX1736EUT41). The EV kit is useful for stand-
alone operation or for applications interfaced with a
microcontroller.

contacting these component suppliers.
Quick Start
The MAX1736 EV kit is a fully assembled and tested
surface-mount board. Follow the steps below for board
operation.
Do not plug in the wall cube to the AC
voltage source until step 4:
1) Verify that a shunt is not across jumper JU1 to
enable the charger.
2) Connect the wall cube鈥檚 output to the power jack
(J1).
3) Place a voltmeter across the BATT+ pad and BATT-
pad.
4) Plug in the wall adapter and verify that the no-load
voltage across BATT+ and BATT- is approximately
2.5V.
5)
Observe the correct Li+ cell polarity.
Connect a
single-cell Li+ battery across the BATT+ and BATT-
terminals of the EV kit.
6) Once the voltage across BATT+ and BATT- reaches
4.2V, the Li+ cell has been charged.
