The MCP73844T-840I/MS from Microchip Technology is an advanced linear charge management controller suitable for space-limited and cost-sensitive applications. This device is designed for Lithium-Ion or Lithium-Polymer battery packs, specifically supporting dual series cell configurations with a preset voltage regulation of 8.4V.
Key features include high-accuracy voltage regulation with a maximum deviation of 0.5%, programmable charge current, and programmable safety timers. It also incorporates preconditioning for deeply depleted cells and automatic end-of-charge control. The controller provides a charge status output for direct LED drive and automatically powers down when input power is removed.
Operating within an ambient temperature range of -40°C to 85°C, the MCP73844T-840I/MS is housed in an 8-pin MSOP package, making it ideal for compact designs. Its input voltage range is specified up to 12V, and it supports battery chemistries like Lithium Ion and Polymer.
This charge management controller is well-suited for applications such as portable data assistants, cellular telephones, hand-held instruments, cradle chargers, digital cameras, and MP3 players, where efficient and reliable battery charging is critical.
