The MCP73831T-2ACI/OTCT-ND is a linear charge management controller designed for single-cell lithium-ion and lithium-polymer batteries. It features an integrated pass transistor and current sense, along with reverse discharge protection. The device offers high-accuracy preset voltage regulation with options of 4.20V, 4.35V, 4.40V, and 4.50V, and allows programmable charge currents ranging from 15 mA to 500 mA. This product includes selectable preconditioning and end-of-charge control options, with a charge status output available in both tri-state and open-drain configurations. It operates over a temperature range of -40¬8C to +85¬8C and is packaged in an 8-lead DFN or a 5-lead SOT-23 format, making it suitable for space-constrained applications. The MCP73831T-2ACI/OTCT-ND is particularly well-suited for portable devices such as personal data assistants, cellular phones, digital cameras, and USB chargers.
