DESCRIPTION
The EV2759-Q-00A is an evaluation board for
the MP2759, a highly integrated switching
charger designed for portable devices with 1-6
cell series Li-ion or Li-polymer batteries pack. It
is able to achieve up to 3A charge current and
support variety of battery chemistry types with
different battery full voltage.
The MP2759 can operate under maximum 36V
DC input voltage. When input power supply is
present, the MP2759 charges the battery with
four phases: trickle-charge, pre-charge,
constant-current charge and constant-voltage
charge.
To guarantee safe operation, the MP2759 has
robust protection functions including: battery
over-voltage protection, battery temperature
sensing and protection, thermal shutdown, and
charging safety timer.

This board is designed for MP2759 which is a highly integrated switching charger for 1-6 cell Li-ion/Li-
Polymer batteries in series. And layout accommodates most commonly used capacitors.
1, Connect the battery pack to BATT and GND connectors, take care that the battery positive/negative
terminal must not be reversely connected.
2, If using a battery emulator, preset the battery emulator to proper voltage and turn off the emulator,
connect to BATT and GND, then turn on the emulator output.
3, Preset an input power source to proper voltage and turn off the power source, connect the power
source to VIN and GND, then turn on the power source. The EVB would start charging.
4, Please confirm that the NTC jumper has been connected, otherwise it would not charge because of
NTC fault.
5, To modify the charging parameters, the EVB offers multiple options to be configured by the jumpers.
The charge current can be selected among 1A/2A/3A
The input current limit can be selected among 1A/1.5A/2A
The cell numbers can be selected among 1s/2s/3s/4s/5s/6s
The battery regulation voltage of each cell can be selected among
3.6V/4.0V/4.15V/4.2V/4.35V/4.4V

The input voltage minimum limit can be selected among 10V/15V/22V/28V.
6, Connect the system load to SYS and GND connectors if you need, take care that the positive/
negative terminal must not be reversely connected.
7, Please take care that the max system load current should not exceed the input source capacity, if the
system load has the possibility of exceeding the input source output current limit, a schottky diode is
required to bypass Q1 body diode.
