The LTC6813ILWE-1#3ZZPBF from Analog Devices is an 18-cell Battery Stack Monitor IC that has been designed for precise and efficient battery management. It requires an input voltage of up to 112.5 V. This IC offers selectable data acquisition rates for reducing noise interference. It enables seamless and high-speed communication over long distances while minimizing susceptibility to RF interference owing to its stackable architecture. This monitoring IC simplifies integration by requiring only one connection to a host processor, ensuring reliable communication integrity even if there is a fault in the chain. It supports both battery-powered and isolated power operation and features built-in passive balancing for each cell and individual control through pulse width modulation (PWM) technique. This IC is available in a surface-mount package that measures 10.25 x 10.25 mm and is ideal for fleet and asset tracking, automotive GPS data loggers, automotive telematics systems, toll collection systems, security systems, and USB-powered device applications.
