MAX1737 Evaluation Kit

General Description

Features

ꢀ Complete Li+ Charging Solution for 1 to 4 Cells

ꢀ Low Heat and High Efficiency

ꢀ 300kHz PWM Operation

ꢀ Up to 28V Input Voltage Range

ꢀ 28-Pin QSOP Package

The MAX1737 evaluation kit (EV kit) is an assembled

and tested PC board that implements a step-down,

switching lithium-ion (Li+) battery charger. It can be set

to charge 1 to 4 series cells. The cell voltage can be set

between 4.0V and 4.4V, using standard 1% resistors,

while maintaining 1% overall regulation accuracy.

The MAX1737 detects faulty cells and terminates

charging. Two capacitors are used to set the charge

termination, prequalification, and fault timeout periods.

Three LEDs indicate the charging status. A user-sup-

plied thermistor can be connected to the MAX1737 EV

kit to monitor battery temperature and suspend charg-

ing for over- and undertemperature conditions.
