    Description

    Product Overview
    This charger board is based on the bq25185 power management IC and is designed for charging single-cell Lithium-Ion, Lithium-Polymer, or LiFePO4 batteries. It supports multiple power sources including USB, DC input, and solar panels. The board also provides power-path management so the load can be powered while the battery is charging.

    It is suitable for portable electronics, battery powered projects, and solar powered systems.

    Supported Battery Types
    • Li-Ion
    • Li-Polymer
    • LiFePO4 (configurable)

    Charging Sources
    • USB Type-C input (5 V)
    • External DC input (5 V to 18 V)
    • Solar panel input (5 V to 7 V recommended)

    Charging Current Options
    • 1 A default
    • 500 mA selectable
    • 250 mA selectable
    (Current is set using onboard jumpers)

    Battery Voltage Configuration
    • 3.7 V nominal / 4.2 V max for Li-Ion and Li-Polymer
    • 3.2 V nominal / 3.65 V max for LiFePO4
    (Battery chemistry selectable using jumpers)

    Power Path Management
    The board automatically manages power between the input source and the battery.
    • Load is powered from USB, DC, or solar when available
    • Excess current is used to charge the battery
    • Battery supplies additional current if load demand exceeds 1 A
    • Supports current spikes up to 3 A from the battery

    Load Output
    • Regulated output, maximum 4.5 V
    • Output voltage follows battery level when input power is removed
    • Output range approximately 3.0 V to 4.5 V

    Indicators and Control
    • Charging status LED
    • Fault indicator LED
    • Power good LED
    • Charger enable pin
    • Charge and fault signal breakout pads

    Thermal Protection
    • Optional external 10K thermistor support
    • Automatically reduces charging current to prevent battery overheating

    Additional Features
    • USB Type-C connector with proper CC resistors
    • Mounting holes for secure installation
    • Battery voltage and load voltage monitoring pads

    Typical Applications
    • Portable electronics
    • Battery powered microcontroller projects
    • Solar powered devices
    • IoT and low power systems
    • Prototyping and development boards

    Usage Notes
    • Designed for single-cell batteries only
    • Load output will never exceed 4.5 V
    • Battery and load voltage drop as battery discharges
    • Solar panels above 7 V provide no benefit and increase heat

    Package Contents
    • bq25185 charger board ×1
