Overview
The MCP3421 Battery Fuel Gauge Demo Board demonstrates how to measure the battery voltage and discharging current using the MCP3421.
The MCU algorithm calculates the battery fuel being used. This demo board is shipped with 1.5V AAA non-rechargeable battery. The demo board displays the following parameters:
- Measured battery voltage.
- Measured battery discharging current.
- Battery Fuel Used (calculated).
The MCP3421 Battery Fuel Gauge Demo Board also can charge a single-cell 4.2V
Li-Ion battery. This feature, however, is disabled by firmware since the demo kit is shipped to customer with non-rechargeable 1.5V AAA battery.
Please contact Microchip Technology Inc if you want to use the battery rechargeable feature.
