MCP73831 ADJUSTABLE LIPO CHARGER

SparkFun Adjustable LiPo Charger

PRT-14380

Description

The SparkFun Adjustable LiPo Charger is a single‐cell lithium

polymer (LiPo) and lithium ion battery charger. Because it’s

adjustable, this charger will be able to safely charge most of our

single‐cell batteries with ease. With its onboard charge rate

selector, you will be able to set the maximum amount of

current to charge your battery from 15mA to 500mA.

Once the board is configured for the battery, you can connect

power from either a microUSB cable or the pins below the USB

connector labeled GND and INPUT. Once power is connected,

you can install a single LiPo battery to one of the three battery

connectors, the JST connector, PTH pins marked BATT, or the

2450 coin cell holder on the back of the board. The input

voltage for the MCP73831 charger IC is between 3.75V and 6V.

To fully charge a LiPo battery, it is recommended to have a

voltage of around 5V. The charge IC will regulate the voltage

down to safely charge the LiPo battery.

Note: The switches on the Adjustable LiPo Charger come

shipped with all the switches in the ON position. Before

configuring the board, all the switches should be moved to the

OFF position.
