TP4056 1A Li-Ion Lithium Battery Charging Module with Current Protection

TP4056 1A Li-Ion Lithium Battery Charging Module with Current Protection is a complete single-cell constant-current/constant-voltage (CC/CV) linear charger and battery protection breakout board for 3.7V (4.2V full charge) lithium-ion and lithium-polymer batteries. Featuring a reversible USB Type-C power input port alongside dedicated solder pads, this module combines the industry-standard TP4056 1A linear charger IC with a DW01A battery protection IC and FS8205A dual N-channel MOSFET. This integrated architecture provides accurate 4.2V charge termination together with active overcharge, over-discharge (2.5V cut-off), and overcurrent/short-circuit load protection.

Key Features:

• USB Type-C & Solder Pad Input: Accepts 5V DC power via a modern reversible USB Type-C receptacle or IN+/IN- through-hole pads.
• Precision 1A CC/CV Charging: Delivers 1000mA constant-current charging with automatic 4.20V ±1.5% constant-voltage termination.
• Integrated DW01A + FS8205A Protection: Safeguards the connected cell against overcharging (>4.3V), deep discharge (<2.4V), and load short circuits (3A limit).
• Soft-Start & Trickle Pre-Charge: Gently revives deeply discharged cells (<2.9V) at 130mA before engaging full 1A charging.
• Dual Status LEDs: Onboard Red LED indicates active charging; Blue/Green LED indicates charge completion.
