The Texas Instruments BQ2019PW is an advanced battery monitoring IC that accurately measures charge and discharge currents in rechargeable battery packs. It is ideal for integration into portable applications such as cellular phones and PDAs, forming the basis of a comprehensive battery-capacity management system.
This IC supports multi-chemistry batteries and is designed for 1 to 3 cell configurations. It features a high-speed 1-wire HDQ serial interface for communication with a host controller. The BQ2019PW operates within a temperature range of -20°C to 70°C and is housed in an 8-lead TSSOP package.
Key features include high-accuracy coulometric charge and discharge current integration, 32 bytes of general-purpose RAM, 96 bytes of flash memory, and an internal temperature sensor. The low power consumption, with operating current less than 80 µA and sleep current less than 1.5 µA, makes it suitable for battery-powered devices.
The BQ2019PW works in conjunction with the host controller in the portable system to implement the battery management system. The host controller interprets the data from the BQ2019PW to communicate meaningful battery data to the end-user or power-management system.
