The MCP73843-420I/MS from Microchip Technology is an advanced linear charge management controller suitable for space-limited and cost-sensitive applications. It is designed for single-cell Lithium-Ion or Lithium-Polymer battery packs, offering a preset voltage regulation option of 4.2V.
Key features include high-accuracy voltage regulation with a maximum deviation of ±0.5%, programmable charge current, and programmable safety charge timers. The device also supports preconditioning of deeply depleted cells, automatic end-of-charge control, and provides a charge status output for direct LED drive. It automatically powers down when input power is removed.
This controller operates within an input voltage range of 4.5V to 12V and is specified for an ambient temperature range of -40°C to 85°C. The MCP73843-420I/MS is supplied in an 8-pin MSOP package, suitable for surface mount applications.
