BQ27350PWR Description

Short technical summary and product information.

The BQ27350PWR from Texas Instruments is a comprehensive battery fuel gauge designed for single-cell and 1-series Li-Ion/Li-Polymer applications. It utilizes the patented Impedance Track™ technology to accurately calculate and report remaining battery capacity, battery voltage, temperature, and charge/discharge current. This IC models the battery discharge curve, automatically adjusting for aging, self-discharge, and temperature/rate inefficiencies to provide up to four time-to-empty predictions.

 

Key features include secure battery authentication using SHA-1/HMAC encryption, a low-value sense resistor requirement (10m or less), and 96-bytes of non-volatile scratchpad data memory. The device supports both HDQ and I2C communication interfaces, making it versatile for various system integrations. It is housed in a 20-pin TSSOP package suitable for surface mounting.

 

Applications for the BQ27350PWR include POS terminals, industrial data collection devices, smartphones, PDAs, digital cameras, and handheld terminals where accurate battery monitoring is crucial. Its ability to provide reliable fuel gauging enhances user experience and device longevity.
