*Static-sensitive device. Unused devices must be stored in conductive material. Protect devices from static discharge and static fields. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to Absolute Maximum Rating Conditions for extended periods may affect device reliability.

The TC3827 is a battery charger controller for a single cell Li-Ion battery. Using an external PMOS transistor, safe
and fast charging of a single Li-Ion cell is accomplished. Features include over-current foldback, charge current monitor, and charge status LED indicator output. An overall system accuracy of 1% ensures that the cell capacity is fully utilized without cycle life degradation. An external resistor sets charge current.

The TC3827 operates with an input voltage range from 4.5V to 5.5V. It is specified over the ambient operating temperature range of 20 to +85 and is available in a space-saving 8-Pin MSOP.
