Description

The MCP73862-I/ML is one member of the MCP7386X series.The MCP7386X family of devices are highly advanced linear charge management controllers for use in spacelimited,cost-sensitive applications. The devices combine high-accuracy, constant voltage and current regulation,cell preconditioning, cell temperature monitoring, advanced safety timers, automatic charge termination,internal current sensing, reverse-blocking protection,charge status and fault indication in either a spacesaving 16-pin, 4 x 4 QFN or 16-pin SOIC package.The MCP7386X provides a complete, fully-functional, standalone charge management solution with a minimum number of external components.

Features of the MCP73862-I/ML are:(1)programmable charge current: 1.2A maximum; (2)programmable safety charge timers; (3)preconditioning of deeply depleted cells; (4)automatic end-of-charge control; (5)optional continuous cell temperature monitoring; (6)charge status output for direct LED drive; (7)fault output for direct LED Drive; (8)automatic power-down; (9)thermal regulation; (10)temperature range: -40 to +85; (11)high-accuracy preset voltage regulation:±0.5%.

The absolute maximum ratings of the MCP73862-I/ML can be summarized as:(1)Vddn:13.5V;(2)storage temperature range:-65 to 150;(3)maximum junction temperature:internally limited;(4)Vbatn, Vset, EN, STAT1, STAT2 w.r.t. Vss:-0.3 to (VDD+0.3)V.Stresses above those listed under "Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied.Exposure to maximum rating conditions for extended periods may affect device reliability.Upon insertion of a battery, or application of an external supply, the MCP7386X family of devices automatically performs a series of safety checks to qualify the charge. The input source voltage must be above the Undervoltage Lockout (UVLO) threshold, the enable pin must be above the logic-high level and the cell temperature must be within the upper and lower thresholds. The qualification parameters are continuously monitored.Deviation beyond the limits automatically suspends or terminates the charge cycle.The input voltage must deviate below the UVLO stop threshold for at least one clock period to be considered valid.
