Description

The bq769x0 family of robust analog front-end (AFE) devices serves as part of a complete packmonitoring

and protection solution for next-generation, high-power systems, such as light electric vehicles, power

tools, and uninterruptible power supplies. The bq769x0 is designed with low power in mind: Sub-blocks

within the IC may be enabled/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.
