The MCP73833-FCI/UN is a 1A output current linear charge Management Controller includes integrated pass transistor, integrated current sensing and reverse discharge protection. It includes safety features such as cell temperature monitoring, on-chip thermal regulation and safety timers. The MCP73833 employs a constant current/constant voltage charge algorithm with selectable preconditioning and charge termination. The constant current value is set with one external resistor. The MCP73833 limits 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.
