BQ26501PW Description

Short technical summary and product information.

The BQ26501PW from Texas Instruments is an advanced gas gauge device designed for handheld and space-limited portable applications. This IC provides highly accurate, standalone monitoring and reporting of battery capacity for single-cell Li-Ion and Li-Pol batteries.

It operates within a temperature range of -20°C to 70°C and utilizes an HDQ (5-kbits/s) one-wire bi-directional serial interface for communication. The device monitors voltage drops across a current sense resistor to determine charge and discharge activity, applying compensations for temperature, self-discharge, and discharge rate to accurately report available capacity.

Key features include automatic battery capacity recalibration, reporting of cell temperature and voltage, and low-power operating modes. The BQ26501PW is housed in a compact 8-TSSOP package, making it suitable for designs where space is a constraint. Applications include PDAs, smartphones, MP3 players, digital cameras, internet appliances, and other handheld devices.
