Renesas Electronics ISL94202IRTZ-T7A, Battery Charge Controller IC, 62μA 48-Pin, TQFN

The ISL94202 is a battery pack monitor IC that supports from three to eight series connected cells. It provides complete battery monitoring and pack control. The ISL94202 provides automatic shutdown and recovery from out-of-bounds conditions and automatically controls pack cell balancing.
The ISL94202 is highly configurable as a stand-alone unit, but can be used with an optional external Microcontroller (MCU), which communicates to the ISL94202 through an I2C interface.
The ISL94202 supersedes the ISL94203 for all future designs, as the ISL94202 operates in both parallel and series power FET configurations.
