Microchip (MCP73842-840I/UN) Battery Charger for 2 Cells of Li-Ion

Battery Charger for 2 Cells of Li-Ion, Li-Pol battery, 9.4V input, 8.4V / 1A charge, MSOP-10

Product Overview
The MCP73842-840I/UN is an advanced dual cell lithium-ion/lithium-polymer Charge Management Controller combines high accuracy constant-voltage (0.5% maximum) constant-current regulation, cell pre-conditioning, cell temperature monitoring, advanced safety timers, automatic charge termination and charge status indication. The device provides a complete, fully functional, stand-alone charge management solution for applications utilizing dual series cell Lithium-Ion or Lithium-Polymer battery packs. Two preset voltage regulation options are 8.2 and 8.4V for use with either coke or graphite anodes. The MCP73842 operates with an input voltage range of 8.7 to 12V and is fully specified over the ambient temperature range of -40 to 85°C.
