with Mode Indicator and Charge Current Monitor
Features Description Linear Charge Management Controller for Single
Lithium-Ion Cells High Accuracy Preset Voltage Regulation:
+ 1% (max) Two Preset Voltage Regulation Options:
-4.1V -MCP73827-4.1
-4.2V -MCP73827-4.2 Programmable Charge Current Automatic Cell Preconditioning of Deeply
Depleted Cells, Minimizing Heat Dissipation During Initial Charge Cycle Charge Status Output for LED Drive or Microcontroller Interface Charge Current Monitor Output Automatic Power-Down when Input Power
Removed Temperature Range: -20В°C to +85В°C Packaging: 8-Pin MSOP The MCP73827 is a linear charge management controller for use in space-limited, cost sensitive applications. The MCP73827 combines high accuracy
constant voltage, controlled current regulation, cell preconditioning, and charge status indication in a space
saving 8-pin MSOP package. The MCP73827 provides
a stand-alone charge management solution. Applications Typical Application Circuit
