3 Description

The Texas Instruments bq40z60 device is a

Programmable Battery Management Unit that

integrates battery charging control output, gas

gauging, and protection for completely autonomous

operation of 2-series to 4-series cell Li-Ion and Li-

Polymer battery packs. The architecture enables

internal communication between the fuel gauging

processor and battery charger controller to optimize

the charging profile based on the external load

conditions and power path source management

during load transients and adaptor current limitations

in the system. The charging current efficiency is

scalable for power transfer based on the external

components, such as the NFETs, inductor, and

sensing resistor.
