The MCP73842-820I/UN from Microchip Technology is a highly advanced linear charge management controller suitable for space-limited and cost-sensitive applications. It is designed for Lithium-Ion or Lithium-Polymer battery packs, specifically supporting dual series cell configurations with a battery pack voltage of 8.2V.
Key electrical features include a high-accuracy preset voltage regulation of ±0.5% maximum. The device supports programmable charge current and safety timers, along with preconditioning for deeply depleted cells and automatic end-of-charge control. It operates within an input voltage range of 8.7V to 12V and maintains functionality across an operating temperature range of -40°C to 85°C.
This controller is available in a 10-MSOP package, suitable for surface mount applications. It provides essential features for battery charging management, including fault protection for over-temperature conditions and a charge status output for direct LED drive. The MCP73842-820I/UN is an ideal solution for applications such as portable data assistants, cellular telephones, and hand-held instruments requiring reliable battery charging.
Environmental compliance includes RoHS3 status as compliant, REACH unaffected, and an MSL of 1. The device is designed for surface mounting, fitting into compact designs.
