Description
The BQ7692006 family of robust analog front-end (AFE) devices serves as part of a complete pack monitoring and protection solution for next-generation, highpower systems, such as light electric vehicles, power tools, and uninterruptible power supplies. The BQ7692006 is designed with low power in mind: Subblocks within the IC may be enabled or disabled to control the overall chip current consumption, and a SHIP mode provides a simple way to put the pack into an ultra-low power state. The BQ7692006 device supports up to 5-series cells or typical 18-V packs.
