## FAQ

    What is the BQ25895 Mini Evaluation Board?

A compact, fully-featured test platform for the **Texas Instruments BQ25895** — 5 A single-cell switch-mode charger with **NVDC power path**, I²C control, USB OTG boost, and high-speed USB data switching.

    What charging current does it support?

Up to **5 A input current** and **3.5 A charging current** from a 5–14 V source (USB PD, QC3.0, or standard adapter). Perfect for fast-charging smartphones and tablets.

    Does it support USB Power Delivery (PD)?

Yes — the BQ25895 natively supports **USB PD** and **QC3.0**. Connect a PD charger to the input USB-C and the chip will negotiate up to 14 V automatically.

    Can I use it as a USB OTG power bank?

Yes — enable **OTG Boost mode** via the dedicated jumper or I²C. The board outputs 5 V / 3 A from the battery on the “Boost Output” pins.

    What is the high-speed USB switch for?

It allows **USB 2.0 data** to pass from the downstream USB-C port directly to your phone/tablet while charging — ideal for debugging or file transfer during fast charging.

    How do I configure the charger (current, voltage, etc.)?

Via **I²C interface** (SCL/SDA pins are broken out). Use any microcontroller (Arduino, ESP32, etc.) or TI’s GUI software with a USB-to-I²C adapter.

    What do the LEDs indicate?

• **PG**: Input power good
 • **CHG**: Charging in progress
 • **DONE**: Charge complete
 • **FAULT**: Fault condition (over-voltage, thermal, etc.)

    Can I disconnect the battery while the system is running?

Yes — thanks to **NVDC power path**. The system load is supplied directly from the input adapter even if the battery is removed.

    Is the board safe for Li-Ion batteries?

Absolutely — includes JEITA, thermal regulation, input OVP, battery OVP, charge timer, and short-circuit protection.

    Can I integrate this board into my own design?

Yes — all critical pins (SYS, BAT, VBUS, OTG, I²C, INT, etc.) are broken out to headers. Use it as a reference design or directly embed it.
