Monitoring IC targets Pb-acid batteries

The bq34z110 gas gauge IC, available in a 14-pin package, is the industry’s only scalable power management device to support multi-cell lead-acid battery packs for battery voltages of 4, 12, 24, 48, and up to 64-V. The lead-acid battery management gas gauge IC uses a proprietary impedance track capacity measurement technology and supports batteries used in mobile and stationary applications including medical instruments, wireless base stations and telecom shelters, e-bikes, inverters, and uninterruptible power supplies.

The battery monitoring gauge constantly informs the user 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. The battery monitoring device is the industry’s first multi-cell scalable battery gauge to support a wide range of lead acid batteries including large capacity batteries (1 Ahr to 65 Ahr) and high-current applications (0 to 32 A). The bq34z110EVM evaluation module, setup configuration, application notes, user guide are available now.
