CN3065 Solar and USB Lithium Battery Charger Module

Description

CN3065 Solar and USB Lithium Battery Charger Module

Easily charge a single 3.7V Li-Ion or Li-Polymer battery from either a USB port or a small solar panel with this compact and efficient charger module . Powered by the CN3065 IC, it’s specifically designed to work with solar panels and other variable power sources, making it a perfect choice for solar-powered and portable electronics projects .

Key Features

• Dual Power Sources: Charge your battery via the Micro-USB port or a solar panel (4.4V ~ 6V DC) .

• Solar-Optimized: An on-chip 8-bit ADC automatically adjusts the charging current based on your solar panel’s output capability, eliminating the need for a complex MPPT circuit .

• Efficient & Integrated: Contains an on-chip power MOSFET, so no external blocking diode or current sense resistor is required .

• Simple Status Indication: Onboard LEDs clearly show the charging state: Red for charging, Green for fully charged .

• Safe and Smart: Features include thermal regulation to prevent overheating, pre-charge conditioning for deeply discharged cells, and an automatic low-power sleep mode to prevent battery drain when no input power is available .

• Convenient Connectors: Comes with JST-PH 2.0mm connectors for the battery, the load, and the solar panel, plus a Micro-USB port for USB power .
