TI launches gas gauge ic for multi cell lead acid batteries
Texas Instruments has introduced the bq34z110, a lead acid battery management gas gauge ic which features the company's proprietary Impedance Track capacity measurement technology.
Available in a small 14pin package, the ic is said to be the industry's only scalable power management device to support multi cell lead acid battery packs with battery voltages of 4, 12 , 24 and 48V.
The device supports batteries used in mobile and stationary applications, including medical instruments, wireless base stations and telecom shelters, e-bikes, inverters and uninterruptible power supplies.
According to TI, the Impedance Track technology constantly informs users about the battery's state of health and state of charge and maintains up to a 95% accurate capacity measurement for the entire life of the battery.
