Series Charge/Discharge Path 3-to-8 Cell Li-Ion Battery Pack Monitor

1. Overview

The ISL94202 is a Li-ion battery 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 external microcontroller, which

communicates to the IC through an I C interface.

1.1

Features

• Eight cell voltage monitors support Li-ion CoO , Li-ion Mn O , and Li-ion FePO chemistries

• Stand-alone pack control - no microcontroller needed

• Multiple voltage protection options (each programmable to 4.8V; 12-bit digital value) and selectable overcurrent

protection levels

• Programmable detection/recovery times for overvoltage, undervoltage, overcurrent, and short-circuit conditions

• Configuration/calibration registers maintained in EEPROM

• Open battery connect detection

• Integrated charge/discharge FET drive circuitry with built-in charge pump supports high-side N-channel FETs

• Cell balancing uses external FETs with internal state machine or external microcontroller

• Enters low power states after periods of inactivity

• Charge or discharge current detection resumes normal scan rates

1.2

Applications

• Power tools

• Battery back-up systems

• Light electric vehicles

• Portable equipment

• Energy storage systems

• Solar farms

• Medical equipment

• Hospital beds

• Monitoring equipment

• Ventilators
