Description

BQ25672RQMR is a Texas Instruments battery-charge-management IC for single-cell Li‑ion/Li‑polymer packs. It combines a switch-mode charger with system-power-path control, allowing charging from USB or other inputs while powering the system.
Key points:
- I2C-controlled, programmable charging: charge current, regulation voltage, and termination.
- Power-path architecture to deliver system power during charging and optimize battery charging.
- Safety protections: overvoltage, short-circuit, overcurrent, overtemperature, reverse-current blocking, and thermistor monitoring.
- Battery preconditioning and automatic recharge.
- Small package (RQMR denotes the specific TI packaging/tape-and-reel option).
Applications: smartphones, wearables, portable instruments, and other single-cell Li‑ion products that require USB charging with integrated power-path management.
Note: For exact electrical specs (input range, max charge current, efficiency) refer to the BQ25672 datasheet and the RQMR package markings.

Package

BQ25672RQMR is in a VQFN-16 package (16-pin, about 3.0 × 3.0 mm, 0.8 mm pitch).

Pinout

- Pin count: 16 pins (QFN-16 package).
- Function: Single-cell Li‑ion battery charger with integrated power-path management (system load powered from input while charging the battery); USB input support with I2C configuration.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- About the company: TI is an American multinational semiconductor company that designs and manufactures integrated circuits and other electronics components, specializing in analog, mixed-signal, and embedded processing ICs.

Application
