MCP73831T-2ATI/OT
Brand: Microchip
MCP73831T-2ATI/OT is a highly integrated linear charge management controller from Microchip for single-cell Lithium-Ion and Lithium-Polymer batteries. The -2ATI variant delivers a regulated 4.2 V charge voltage with programmable charge current up to 500 mA, making it ideal for USB-powered and space-constrained portable applications. It features automatic charge termination, preconditioning of deeply discharged cells, charge status output, and over-voltage protection. Requiring minimal external components and housed in a compact SOT-23-5 package, it operates from a maximum 6 V input over -40 °C to +85 °C.
