Texas Instruments Incorporated has introduced the first lead-acid battery management gas gauge integrated circuit with TI's proprietary Impedance Track capacity measurement technology. The company says its bq34z110 gas gauge IC, which comes in 14-pin package, is the industry's only scalable power management device to support multi-cell lead-acid battery packs with battery voltages of 4 V, 12 V, 24 V, 48 V and higher. The highly accurate, simple-to-use gauge supports batteries used in mobile and stationary applications like medical instruments, wireless base stations and telecom shelters, e-bikes, inverters and uninterruptible power supplies (UPS).

Features and benefits of bq34z110:
Industryís first multi-cell scalable battery gauge to support a wide range of lead acid batteries (4 V to 64 V), including large capacity batteries (1 Ahr to 65 Ahr and higher) and high-current applications (0 A to 32 A and higher).
95-percent accurate battery capacity measurement with TI's Impedance Track proprietary algorithm, which uses current, voltage measurements, temperature and battery characteristics to determine battery state-of-charge, state-of-health and capacity.
Easy setup configuration with application notes, user guide and bq34z110EVM evaluation module.
Battery management for any battery chemistry TI provides battery charge management and capacity monitoring integrated circuits that meet the power requirements of any battery chemistry -- from the smallest coin-cell to the largest multi-cell battery pack. In addition to the bq34z110 gas gauge, TIís 10-A bq24650 and bq24450 charger ICs support battery charge management to multi-cell lead-acid batteries. TI also introduced the bq34z100 lithium-based multi-chemistry, multi-cell battery gas gauge, which supports a wide range of lithium-ion and lithium iron phosphate chemistries in 1- to 16-cell batteries.
