TP4062 (600mA Electronic Cigarette Linear Lithium-ion Battery Charger) DATASHEET
■TP4062 is a complete single cell lithium-ion battery charger suitable for e-cigarette solutions, equipped with positive and negative pole reverse protection, with a larger charging current of 600mA and more stable current consistency. It adopts constant current/constant voltage linear control, SOT packaging, and fewer external components, making TP4062 an ideal choice for portable applications.
■Due to the use of an internal PMOSFET architecture and an anti reverse charging circuit, there is no need for external detection resistors and isolation diodes. Thermal feedback can automatically adjust the charging current to limit the chip temperature during high-power operation or high ambient temperature conditions. The full charge voltage is fixed at 4.2V, and the charging current can be externally set through a resistor. When charging enters the constant voltage stage, the charging current will automatically decrease. When the charging current drops to 1/10 of the set value, the indicator light can indicate a fully charged state, but the charging current will be in a float state until the battery is fully charged to 4.2V.
■When the input voltage (AC adapter or USB power supply) is removed, TP4062 automatically enters a low current state, and the battery leakage current is below 2μA. Other features of TP4062 include a charging current monitor, undervoltage lockout, and two status pins used to indicate the end of charging and input voltage connection.
