BQ35100PWR Description

Short technical summary and product information.

The BQ35100PWR from Texas Instruments is an active battery fuel gauge IC specifically designed for non-rechargeable batteries, particularly primary lithium chemistries like Li-SOCl2 and Li-MnO2. It functions as an end-of-service monitor, providing critical battery health and service life information.

This IC offers accurate measurements of voltage, temperature, current, and coulomb count. It features state-of-health (SOH) algorithms for Li-MnO2 and end-of-service (EOS) algorithms for Li-SOCl2, along with a coulomb accumulation (ACC) algorithm applicable to all battery types. The device boasts ultra-low average power consumption, maximizing battery run time, with specific typical values for SOH (~0.06 µA), EOS (~0.35 µA), and ACC (~0.3 µA) diagnostic updates.

Communication is handled via an I2C interface, allowing host access to battery parameters and status. The BQ35100PWR supports a battery capacity range from 100 mAh to 32000 mAh and operates across a temperature range of -40°C to 85°C. It is housed in a 14-TSSOP package and is suitable for surface mount applications. Additional features include SHA-1 authentication to help prevent counterfeit battery use and configurable host interrupts for diagnostics and failure analysis.
