MCP73837/8 AC/USB Evaluation Board User’s Guide
2.3
GETTING STARTED
The MCP73837/8 AC/USB Dual Input Battery Charger Evaluation Board is fully
assembled and tested for charging a single-cell Li-Ion or Li-Polymer battery with a
regulated 5V AC-Adapter or USB-Port.

Power Input and Output Connection
POWERING THE MCP73837/8 AC/USB DUAL INPUT BATTERY
CHARGER EVALUATION BOARD
1. Connect the positive battery terminal to V BAT+ and negative battery terminal to
V BAT- .
2. Connect the DC power supply Negative Terminal to GND.
3. Connect the 5V DC power supply Positive Terminal to V AC for AC-Adapter Power
Source.
4. Connect the DC power supply Negative Terminal to GND.
5. Connect the 5V DC power supply Positive Terminal to V USB for USB-Port Power
Source.
6. It should initiate the battery charging cycle when either power source is present.
When both power sources are present, the AC-Adapter Power Source will
provide the input power.
7. Position the DIP Switch high for maximum up to 500 mA charge rate and low for
maximum up to 100 mA charging rate. Charging current should be able to read
off multi-meter that is in series with battery.
Note:
The battery can be replaced with test circuit or electronic load that can sink
current with DC power supply.
8. For MCP73838, TE pull low to enable the internal safety timer while high to
disable the internal safety timer.
9. Fast Charge Current can be programmed with various resistors that based on
the Figure 2-1 .
