Charge current is constant and programmable up to a maximum of 1.1A, with programmable current and timer features that let you set the charge profile via external components. Housed in a 10-VFDFN Exposed Pad package (3x3 mm DFN), the MCP73223-C2SI/MF is a surface-mount part with a supplier device package of 10-DFN (3x3). Supplied in Tube format, not tape-and-reel — factor this into the pick-and-place setup if the line expects reel-fed parts. ## Active production and compliance posture ROHS3 Compliant per the manufacturer's declaration, with no exemptions that would block EU-market shipments. Supply voltage max is 16V — the input rail should be regulated to stay below that ceiling, especially during hot-plug or transient events where the input capacitor rings above the supply.","metaTitle":"Microchip MCP73223-C2SI/MF LiFePO4 Charger, 1.1A, 10-DFN","metaDescription":"Active Microchip MCP73223-C2SI/MF LiFePO4 battery charge controller. 1-2 cells, 7.2V pack, 1.1A max charge, 10-DFN.
