Description

The ISL94203 is a Li-ion battery monitor IC that supports from 3 to 8 series connected cells. It provides full battery monitoring and pack control. The ISL94203 provides automatic shutdown and recovery from out of bounds conditions and automatically controls pack cell balancing. The ISL94203 is highly configurable as a stand-alone unit, but can be used with an external microcontroller, which communicates to the IC through an I2C interface.
