MCP1630V Bidirectional 4 Cell Li-Ion Charger Reference Design User’s Guide
2.6
GETTING STARTED
The MCP1630V Bidirectional 4 Cell Li-Ion Charger Reference Design is fully
assembled and tested for charging a four series cell Li-Ion battery pack (Battery Pack
should have internal overvoltage, overcurrent and overtemperature protection). The
board requires the use of an external input voltage source (+7.0V) for charging.

Power Input and Output Connection
POWERING THE MCP1630V BIDIRECTIONAL 4 CELL LI-ION
CHARGER REFERENCE DESIGN
1. Connect the positive side of the +6.5V to +7.0V input to J2 Pin 2, connect the
negative side (or ground) to Pin 1 of J2. This source voltage should not exceed
7.0 and be rated for 8A minimum supply current.
2. Connect the positive side of the Four cell Li-Ion battery pack voltage to J1 Pin 1,
connect the battery pack return to the negative side of J1 Pin 2.
Note:
Both supplies should have a separate isolated return (ground), there is a
current sense resistor between the +7.0V (V BULK ) and +14V(V BATT ) supply
returns. If the returns are connected, the charge current can not be
controlled.
3. Once the SW1 push button is pressed, the MCP1630V Bidirectional 4 Cell Li-Ion
Charger Reference Design is powered. When powered, a charge cycle will start
automatically if the 7.0V is connected and all preconditions are meet, (see
4. LED D3 will be illuminated when the board is running, (charging or bucking).
5. LED D5 will flash only when a charge cycle is in progress.
6. Again, a subsequent pressing of the SW1 push button during normal operation
of the MCP1630V Bidirectional 4 Cell Li-Ion Charger Reference Design will
power-off the converter.
