BQ25125YFPR Description

Short technical summary and product information.

The BQ25125YFPR from Texas Instruments is a low IQ, highly integrated battery charge management solution tailored for wearables and IoT applications. This IC supports multi-chemistry Li-Ion/Li-Polymer batteries and features a configurable charge current of up to 300mA.

 

Key electrical specifications include an input voltage range of 3.4V to 5.5V with a 20V tolerance, and a battery charge voltage range of 3.6V to 4.65V. The device offers a typical quiescent current of 700nA with the buck converter enabled and less than 50nA in ship mode, maximizing battery life. It communicates via an I2C interface, allowing control over charge voltage, current, termination current, and other parameters.

 

Packaged in a compact 25-DSBGA (YFP) format, the BQ25125YFPR is designed for surface mounting. Its small footprint and high integration minimize the need for external components, making it suitable for space-constrained designs. The operating temperature range is -40°C to 85°C.

 

Features such as IC thermal regulation, input overvoltage protection, an integrated LDO, and a configurable buck regulator enhance system reliability and performance. The device also includes power path management for simultaneous system operation and battery charging.
