BQ26231PW Description

Short technical summary and product information.

The BQ26231PW from Texas Instruments is a cost-efficient Coulomb counter peripheral integrated into an 8-pin TSSOP package. This IC works in conjunction with an intelligent host controller to provide state-of-charge information for rechargeable batteries, including Li-Ion, Li-Pol, and NiMH chemistries. It measures the voltage drop across a low-value series sense resistor to determine battery capacity.

 

Key features include a single-wire HDQ serial interface, an operating temperature range of -20°C to 70°C, and low power consumption with operating current typically below 80 µA and sleep current below 10 µA. The device supports multi-chemistry batteries and is ideal for portable applications with non-removable rechargeable battery packs.

 

The BQ26231PW is housed in an 8-TSSOP package suitable for surface mounting. Its design aims to improve accuracy through internal offset calibration and an internal temperature sensor, eliminating the need for external components like a thermistor or crystal oscillator. The device measures signals less than 12.5 µV, enhancing precision in capacity monitoring.
