TP4056 Charging Module 5V 1A Micro USB With Current Protection Charger Li-Ion Lithium Lipo 18650 AA AAA 3.7V Batteries Charging Circuit board
This module uses the TP4056 Li-Ion charge controller IC and a separate protection IC. There are other types of modules on the market that use the TP4056 but lack any protection circuits or ICs to provide the necessary protection needed with lithium batteries. This module uses both the TP4056 and the DW01A Li-Ion battery protection IC, which together in combination provide the following protection features
Manage the constant current to constant voltage charging of a connected lithium battery. Over-discharge protection – keeps your battery from being discharged below 2.4V, a healthy minimum voltage level for your battery. If a connected battery has been discharged below 2.4V the module will cut output power from the battery until the battery voltage has been re-charged above 3.0V (the over-discharge release voltage), which at that time the module will again allow discharge of power from the battery to a connected load. Although the module cuts output power from the battery during an over-discharge situation, it still allows charging of the battery to occur through the parasitic diode of the discharge control MOSFET (FS8205A Dual MOSFET).
Overcharge protection – the module will safely charge your battery to 4.2V, Overcurrent and short-circuit protection – the module will cut the output from the battery if the discharge rate exceeds 3A or if a short-circuit condition occurs, Soft-start protection limits inrush current, Trickle charge (battery reconditioning) – if the voltage level of the connected battery is less than 2.9V, the module will use a trickle charge current of 130mA until the battery voltage reaches 2.9V, at which point the charge current will be linearly increased to the configured charge current.
