TP4056 1A Li-ion Battery USB C Charging Module

TP4056 Chip:

• The TP4056 is a highly integrated charging IC designed specifically for charging single-cell lithium-ion batteries.
• It includes essential functions like constant current (CC) and constant voltage (CV) charging modes, ensuring safe and efficient charging of lithium-ion batteries.
• It also provides overcharge protection, over-discharge protection, and short-circuit protection to ensure the battery's safety during the charging cycle.

Charging Current (1A):

• The module provides a 1A charging current, which is suitable for most small to medium-capacity Li-ion batteries (typically ranging from 500mAh to 3000mAh).
• The charging current can be adjusted if needed by changing a specific resistor on the module.

USB-C Input:

• The module features a USB-C input for charging, which allows for more reliable, faster, and reversible connections compared to the older USB micro-B or Type-A connectors.
• USB-C allows for higher power transfer and faster charging compared to previous USB standards, making it ideal for modern electronic devices and power systems.

Battery Charging and Protection:

• Integrated Protection: The TP4056 includes built-in protections like overvoltage protection, undervoltage lockout, overcharge protection, and thermal shutdown, ensuring the battery and charging process are safe.
• Status Indicators: Many modules include LED indicators to show the charging status: typically, a red LED shows charging, and a green LED shows when the battery is fully charged.

Constant Current / Constant Voltage (CC/CV) Charging:

• The TP4056 operates in two phases:
  • Constant Current (CC): Initially, the charging process uses constant current to charge the battery.
  • Constant Voltage (CV): As the battery voltage approaches its nominal value, the charging switches to constant voltage, allowing the battery to finish charging safely.

Overcharge Protection:

• It ensures the battery doesn't overcharge by cutting off the charging when the battery reaches its safe maximum voltage (usually 4.2V for Li-ion batteries).

Discharge Protection (optional):

• Some TP4056 modules include a discharge protection feature, preventing over-discharge of the connected battery, which can extend battery life.

Efficient Charging:

• The module is designed for efficient charging and can work from a 5V power source, typically provided by the USB-C connection. This makes it easy to integrate into any system that uses a USB-C power source.
