The BQ26220PW from Texas Instruments is an advanced battery monitoring device designed for accurate charge and discharge current measurement in rechargeable battery packs. It is intended for pack integration and forms the basis of a comprehensive battery capacity management system in portable applications.
Key features include a high-accuracy coulometric charge and discharge current integration with automatic offset compensation. The device provides accurate battery voltage and temperature measurement, along with state of charge information for rechargeable batteries. It utilizes an 11-bit analog-to-digital converter for reporting battery voltage with gain and offset correction.
The BQ26220PW operates with an intelligent host controller, communicating via a single-wire HDQ serial interface. It has an operating temperature range of -20°C to 70°C and is housed in an 8-lead TSSOP package suitable for surface mounting.
This IC is designed to work with the host controller in portable systems to implement the battery management system. The host controller interprets the data from the BQ26220PW to communicate meaningful battery data to the end-user or power management system.
