Content for TC4056A

TC4056A It is a complete single lithium-ion battery with a constant current / constant-voltage linear charger. Bottom finned ESOP8 / DIP8 With fewer number of external elements such that the package 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. When the input voltage (AC adapter or USB Power) is removed when, TC4056A Automatically enters a low current state, the drain current to the battery 2uA the following. TC4056A When a power supply may be placed in shutdown mode, reducing the supply current is reduced to 55uA . TC4056A Other features include a battery temperature detection, undervoltage lockout, automatic recharge and two for indicating the charging end led State pin.
