BQ25120YFPR Description

Short technical summary and product information.

The BQ25120YFPR from Texas Instruments is a highly integrated battery charge management solution designed for wearables and IoT applications. This IC supports single-cell Lithium Ion/Polymer batteries, offering a maximum charge current of 300mA. It operates within an input voltage range of 3.4V to 5.5V, with an absolute maximum input voltage tolerance of 20V.

 

The device features an I2C interface for control and configuration, allowing for programmable charge voltage and current settings. Key features include battery temperature thermistor monitoring, IC thermal regulation, an integrated LDO, and a buck converter. The buck regulator is configurable with a default 1.8V output and can provide up to 300mA. It also includes Power Path Management, enabling system power and battery charging simultaneously, and a ship mode with less than 50nA quiescent current for extended shelf life.

 

Packaged in a compact 25-DSBGA (2.5mm x 2.5mm) with minimal external components required, the BQ25120YFPR is suitable for space-constrained designs. It offers features like push-button wake-up and reset, and fault protection against over-temperature, over-voltage, and short circuits. Note that this part is not recommended for new designs; consider alternate products with upgraded functionality.
