Antwire TP4056 Micro USB Lithium Battery Charger Module Charging Board

Micro USB 5V 1A 18650 TP4056 Lithium Battery Charger Module Charging Board WithProtection Dual FunctionsThe TP4056 is a complete single-cell Li-Ion battery with a constantcurrent/constant voltage linear charger. The SOP40 package with heatsink on thebottom of the TP4056 and fewer external components make the TP4056 ideal forportable applications. The TP4056 is suitable for USB power and adapter powersupplies.Due to the internal PMOSFET architecture and anti-reverse charging path, noexternal isolation diodes are required.Thermal feedback automatically adjusts the charge current to limit chiptemperature during high power operation or high ambient temperature conditions.The charging voltage is fixed at 4.2V, and the charging current can beexternally set by a resistor. When the charging current drops to the set valueof 1/10 after reaching the final float voltage, the TP4056 will automaticallyterminate the charging cycle. When the input voltage (AC adapter or USB power)is removed, the TP4056 automatically enters a low current state, reducing thebattery leakage current to less than 2uA. The TP4056 can also be placed inshutdown mode when there is a power supply, reducing the supply current to 55uA.Other features of the TP4056 include battery temperature sensing, undervoltagelockout, automatic recharge, and two LED status pins for charging andtermination. * Battery-18650 * 100% brand new and high quality * Charge module- Linear charging. * Current- 1A adjustable. * Charge precision- 1.5%. * Input voltage- 4.5V-5.5V. * Full charge voltage- 4.2V. * Led indicator- red is charging Green is full charged. * Input interface- micro USB. * Work temperature- -10° to +85°. * Inversed polarity- NO. * Size: small to 25X19X10mm
