TP4069 (10mA-800mA Linear Li-lon Battery Charger) DATASHEET
■TP4069 is a complete single cell lithium battery charger with a single chip positive and negative pole reverse protection, compatible with charging currents ranging from 10mA to 800mA., and it includes trickle, constant-current and constant-voltage. Its SOT23-6、DFN2*2-6 package and low external component count make the TP4069 ideally suited for portable applications. TP4069 is suitable for working with USB power supplies and adapter power supplies. Internally, thermal feedback is used to automatically adjust the charging current, in order to limit the chip temperature during high-power operation or high ambient temperature conditions. The charging current can be set externally through a resistor. When the battery reaches the preset voltage and the charging current drops to 1/10 of the set value, TP4069 will automatically terminate charging.
■When the input voltage (AC adapter or USB power supply) is removed, TP4069 automatically enters a low current state, and the battery leakage current is at 1 μ Below A. Other features of TP4069 include power adaptive, undervoltage lockout, automatic recharging, battery temperature protection function, and a status pin for indicating charging.
■TP4069 adopts SOT23-6 package with a charging current range of 10mA-600mA, and DFN2*2-6 package with a charging current range of 10mA-800mA.
