TC4056A datasheet


The TC4056A is a complete single lithium-ion battery with a constant current / constant-voltage linear charger. 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.

Features :

1. Up 1000mA Programmable charge current
2. No need MOSFET , Sense resistor or blocking diode
3. A single lithium-ion batteries, using SOP Complete Linear charger package
4. Accuracy ± 1.5% of 4.2V Predetermined charge voltage
5. Current monitor for detecting the output of battery
6. Automatic recharge
7. Dual output state of charge, and fault-free battery status display
8. Current supply in the standby mode 55uA
9. 2.9V Trickle Charge version
10. Soft-start limits inrush current
