Multi-Cell Li-Ion Battery Manager

ISL94212

Features

The ISL94212 is a Multi-cell Li-ion battery manager IC that

supervises up to 12 series connected cells. The part performs

accurate monitoring, cell balancing and extensive system

diagnostics functions. Three cell balancing modes are

provided: manual mode, timed mode and an auto-balance

mode which terminates balancing functions when a (host

microcontroller specified) charge transfer value has been met.

• Up to 12-cell voltage monitors, support Li-Ion CoO , Li-Ion

Mn O , and Li-Ion FePO4 chemistries

• Cell voltage measurement accuracy ±10mV

• Cell voltage scan rate of 19.5µs per cell (234µs to scan

12 cells)

• Up to four external temperature inputs

• Robust Daisy Chain communications system

The ISL94212 communicates to a host microcontroller via an

SPI interface and to other ISL94212s using a robust,

proprietary, two-wire Daisy Chain system.

• Integrated system diagnostics for all key internal functions

• Hardwired and communications based fault notification

The ISL94212 is offered in a 64 Ld TQFP package and is

specified over an industrial temperature range of -40°C to

+85°C.

• Integrated watchdog shuts down device if communication is

lost

• 7µA shutdown current: Enable = V

• 2Mbps SPI

Applications

• Hybrid, electric vehicle battery packs

• Battery backup systems

• E-Moto; E-Bike
