The MCP73841T-420I/UN from Microchip Technology is a highly 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. This device operates with an input voltage range of 4.5V to 12V and is fully specified over an ambient temperature range of -40°C to +85°C.
Key features include high-accuracy preset voltage regulation with a maximum deviation of ±0.5%. The controller supports programmable charge current and safety timers, preconditioning for deeply depleted cells, and automatic end-of-charge control. It also includes a charge status output for direct LED drive and automatic power-down when input power is removed.
The MCP73841T-420I/UN is supplied in a 10-MSOP package, designed for surface mounting. Its fault protection includes over-temperature monitoring. This component is ideal for applications such as personal data assistants, cellular telephones, hand-held instruments, cradle chargers, digital cameras, and MP3 players requiring reliable battery charging management.
