GETTING STARTED
The MCP1630 Low-Cost NiMH Battery Charger is fully assembled and tested for
charging three series cell NiMH batteries. The charge termination is based on a
negative slope in battery voltage or a positive slope in battery pack temperature, (when
external thermistor is installed). This board requires the use of an external voltage
source to charge the series connected batteries with a range of +6V to +14V input. An
external load and thermistor is also required to evaluate the charger reference design.
