The BMS025 evaluation module (EVM) is a complete charger module for evaluating an I
2
C-controlled,
single-cell NVDC charge using any of the devices listed above.
This EVM does not include an EV2300/EV2400 interface board. To evaluate the EVM, an
EV2300/EV2400 interface board must be ordered separately.

Description
J1(2) –VIN
Positive rail of the charger input voltage
J1(1) –GND
Ground
J2(1) – SYSTEM
Positive rail of the charger system output voltage, typically connected to the system
load
J2(2) –GND
Ground
J3(1) –PMID
Positive rail of the charger output voltage for power bank applications in reverse boost
mode (OTG). This output also shares the rail with the VIN input rail in forward buck
mode
J3(2) –GND
Ground
J4(3) –BATTERY Positive rail of the charger battery input, connected to the positive terminal of the
external battery
J4(2) – BATSNS
Input connected to the positive node of the battery for remote cell voltage
measurement
J4(1) - GND
