Texas Instruments has introduced bq34z110 gas gauge IC for measuring battery charge levels in multi-cell lead-acid battery packs with battery voltages of 4 V, 12 V, 24 V, 48 V and higher. The applications suggested includes medical instruments, wireless base stations and telecom shelters, e-bikes, inverters and uninterruptible power supplies (UPS).
bq34z110 gauge with Impedance Track technology constantly informs a user about the battery's state-of-health and state-of-charge and maintains up to a 95-percent accurate capacity measurement for the entire life of the battery.
bq34z110 supports large capacity batteries (1 Ahr to 65 Ahr and higher) and high-current applications (0 A to 32 A and higher).
Availability and pricing: The bq34z110 fuel gauge for lead acid-based batteries is available now in a 14-pin, 5-mm x 6-mm TSSOP package, priced at US$2.30 in quantities of 1,000. The bq34z110EVM is available through TI eStore for US$49.
