The BQ26221PWR from Texas Instruments is an advanced battery monitoring integrated circuit. It is designed to accurately measure charge and discharge currents in rechargeable battery packs, making it suitable for portable applications like cellular phones and PDAs.
Key features include an 11-bit Analog-to-Digital Converter (ADC) for precise battery voltage and temperature measurements, with gain and offset correction. It provides high accuracy coulometric charge and discharge current integration with automatic offset compensation. The device includes 32 Bytes of General Purpose RAM, 96 Bytes of Flash memory, and 8 Bytes of ID ROM for data storage.
This IC communicates directly with the HDQ engine in TI OMAP processors via a single-wire HDQ serial interface. It operates at low power, with an operating current of 30 µA, sleep current of 1 µA, and hibernate current of 600 nA. The internal temperature sensor eliminates the need for an external thermistor, and a high-accuracy internal timebase removes the requirement for an external crystal oscillator.
The BQ26221PWR is housed in an 8-lead TSSOP package and is designed for surface mount applications. It operates within a temperature range of -20°C to 70°C.
