MICROCHIP - MCP73831T-2ACI/OT - IC zum Laden von 1-zelligen Li-Ionen- & Li-Polymer-Akkus, 6V Eingang, 4.2V/500mA, SOT-23-5
The MCP73831T-2ACI/OT employs a constant-current/constant-voltage charge algorithm with selectable preconditioning and charge termination. This article is going to introduce pinout, applications, features, and more details about MCP73831T-2ACI/OT.
MCP73831T-2ACI/OT
The MCP73831T-2ACI /OT devices are highly advanced linear charge management controllers for use in space-limited, cost-sensitive applications. The MCP73831T-2ACI /OT is available in an 8-Lead, 2 mm x 3 mm DFN package or a 5-Lead, SOT-23 package. Along with their small physical size, the low number of external components required make the MCP73831T-2ACI /OT ideally suited for portable applications. For applications charging from a USB port, the MCP73831T-2ACI /OT adheres to all the specifications governing the USB power bus.
The MCP73831T-2ACI/OT employs a constant-current/constant-voltage charge algorithm with selectable preconditioning and charge termination. The constant voltage regulation is fixed with four available options: 4.20V, 4.35V, 4.40V, or 4.50V, to accommodate new, emerging battery charging requirements. The constant current value is set with one external resistor. The MCP73831T-2ACI/OT devices limit the charge current based on die temperature during high power or high ambient conditions. This thermal regulation optimizes the charge cycle time while maintaining device reliability.
