product description
TC4056A It is a complete single lithium-ion battery with a constant current / constant-voltage linear charger. Bottom finned ESOP8 with DIP8 Package, with low external component count of such TC4056A Ideal for portable applications. TC4056A You can fit USB Power adapter and power supply.
As a result of internal PMOSFET Architecture, coupled with anti-down charge circuit, so that no external blocking diode. Thermal feedback to automatically adjust the charging current to limit the die temperature during high power operation or high ambient temperature conditions. The charge voltage is fixed at 4.2V , The charge current can be set by an external resistor. When the charge current drops to the final value after reaching float voltage 1/10 Time, TC4056A The charge cycle is automatically terminated.
