Product details

Active production – sourcing posture

The BQ25616JRTWR: ROHS3 compliant.

3A charge current and 13.5V input ceiling

Supply voltage max is 13.5V, which covers USB VBUS (5V), USB-C PD up to 9V, and common 12V wall adapters. The input OVP fault protection kicks in above that ceiling, so the part survives adapter spikes without external clamp diodes.

Industrial temp range and package thermal path

That means the charger can live in an outdoor enclosure, a garage EVSE, or a portable tool battery pack without derating for ambient heat. Housed in a 24-WQFN with exposed pad, 4x4 mm body. No lab bench needed — a reflow profile for standard lead-free solder works.

USB interface and programmable current

The interface is USB, meaning it handles the enumeration and current negotiation typical of USB battery chargers — no external microcontroller needed for basic charge management. Charge current is programmable via an external resistor. The datasheet provides the resistor value vs. current table; a single resistor sets the constant-current phase. No I2C or SMBus required.

Frequently asked questions

What is the difference between BQ25616JRTWR and BQ25616?

The BQ25616JRTWR is a specific reel-tape variant of the base BQ25616 family. The base product number BQ25616 covers the same charger core; the 'JRTWR' suffix denotes the 24-WQFN package and tape-and-reel packaging. Electrical specs — 3A charge, 13.5V input, USB interface — are identical across the family.
