ISL94203開發(fā)板套件編程器的評估演示板及套件規(guī)格書PDF中文資料

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.

Features

? Eight cell voltage monitors support Li-ion CoO2, Li-ion

Mn2O4 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

? 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

Applications

? Power tools

? Battery back-up systems
