MCP73871 Demo Board with Voltage Proportional Current Control (MCP73871DM-VPCC)
The MCP73871 Demo Board with Voltage Proportional Current Control is designed to demonstrate Microchip's stand-alone linear Li-Ion battery charger with system power path and load sharing management control solution. The MCP73871 integrates the required elements to meet design challenges when developing new Li-Ion / Li-Polymer batteries powered products.
The MCP73871 Demo Board with Voltage Proportional Current Control is designed to deliver minimum 1.5A total current to system load and to a single cell Li-Ion battery at 4.2V preset voltage regulation (4.1V, 4.35V and 4.4V options are also available for MCP73871). The board has a dip switch helping to decides the input power source between AC-DC wall adapter and USB port (AC/USB) and control input current limits, enable charge timer and enable charging.
The MCP73871 Demo Board with Voltage Proportional Current Control comes with a factory preset low-battery indicator (LBO) when input is absent. The preset value is 3.2V and STAT1 LED (green) with turn ON if the battery voltage is below the threshold voltage.
