TP4056 Usb Micro Lithium Battery Charger and Protection Module

The TP4056 is a complete constant-current/constant-voltage linear charger for single-cell lithium-ion batteries. It is designed for compact and cost-sensitive portable applications. The TP4056 offers various features that make it suitable for safe and efficient battery charging.
Input Voltage: Typical input voltage range: 4.5V to 5.5V, suitable for USB power.
Charge Current: Programmable charge current up to 1A.
Constant-Current/Constant-Voltage Charging: Ensures efficient charging with a constant current until the battery reaches a certain voltage, then switches to constant voltage to complete the charging process.
Automatic Recharge: The TP4056 will automatically restart the charge cycle if the battery voltage drops below a certain threshold.
Battery Overcharge Protection: Prevents the battery from being charged beyond its maximum voltage, typically 4.2V.
Thermal Regulation: Limits the charging current to maintain a safe temperature during operation.
Status Indication: LED indicators for charge status: charging, fully charged, and fault.
Reverse Polarity Protection: Protects the device if the battery is connected with reverse polarity.
