3-to-8 Cell Li-ion Battery Pack Monitor

ISL94203

Features

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.

• Eight cell voltage monitors support Li-ion CoO , Li-ion

Mn O , and Li-ion FePO4 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

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 I C interface.

• Programmable detection/recovery times for overvoltage,

undervoltage, overcurrent, and short circuit conditions

• Configuration/calibration registers maintained in EEPROM

• Open battery connect detection

Applications

• Power tools

• Integrated charge/discharge FET drive circuitry with built-in

charge pump supports high-side N-channel FETs

• Battery back-up systems

• E-bikes

• 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
