FEATURES
The MCP3421 Battery Fuel Gauge Demo Board has the following features:
• Measure the battery voltage and display the result on LCD.
• Measure the current coming out from the battery (discharging current) or coming
• Calculate the battery fuel that has been used and display the result on LCD.
• Turn on beep sounds if the battery is used more than 50% of its initial value, or the
The MCP3421 Battery Fuel Gauge Demo Board includes a 9V and 1.5V AAA batteries.
Please make sure the positive lead of the 1.5V battery holder is connected to TP9 and
the negative lead (black) is connected to the GND terminal.
The U1 and U5 devices may get damaged if the polarity of the battery connection is
reversed. If the connection is accidently reversed, replace the U1 and U5 devices in
order to obtain accurate measurements.

Note:
The charging current is only available when the battery charging mode is
enabled.
The MCP3421 Battery Fuel Gauge Demo Board can be also configured
very easily for other sensor output measurements. Just connect the sensor
output at the ADC input terminal. The LCD will display the voltage.
