Li-Ion System PPM Reference Design
2.3
GETTING STARTED
The Li-Ion Battery Charger System Power Path Management Reference Design is fully
assembled and tested for charging a single-cell Li-Ion or Li-Polymer battery with or
without system load.
2.3.1
2.3.1.1
Power Input and Output Connection
POWERING THE LI-ION BATTERY CHARGER SYSTEM POWER PATH
MANAGEMENT REFERENCE DESIGN
1. Connect the positive battery terminal to V BAT+ and negative battery terminal to
V BAT- .
2. Connect the 5V DC power supply Negative Terminal to V SS .
3. Connect the 5V DC power supply Positive Terminal to V DD .
4. It should initiate the battery charging cycle when the power source is present.
5. Position the DIP Switch to “H” for 400 mA fast charge current rate of MCP73832
and 1000 mA fast charge current rate of MCP73833.
6. Position the DIP Switch to “L” for 25 mA fast charge current rate of MCP73832
and 50 mA fast charge current rate of MCP73833.
Note:
Note:
Fast Charge Current can be programmed with various resistors that based
The Li-Ion battery pack can be replaced with test circuit or electronic load
7. Connected positive of load to System Load on the board and negative of load to
either V SS or V BAT- . The load can be a power resistor or E-Load.
8. Remove DC power supply, the load should be supported by the Li-Ion battery
now.
Note:
MCP73832 circuit is labeled “A” on the reference design while MCP73833
circuit is labeled “B” on the reference design.
