DESCRIPTION
The bq26200 is an advanced battery monitoring IC
designed to accurately measure the charge and
discharge currents in rechargeable battery packs.
Intended for pack integration, the bq26200 contains all
the necessary functions to form the basis of a
comprehensive battery capacity management system
in portable applications such as cellular phones, PDA’s,
or other portable products.
The bq26200 works with the host controller in the
portable system to implement the battery management
system. The host controller is responsible for
interpreting the bq26200 data and communicating
meaningful battery data to the end-user or power
management system.
The bq26200 provides 64 bytes of general-purpose
flash memory, 8 bytes of ID ROM and 32 bytes of flash
backed RAM for data storage. The non-volatile memory
can maintain formatted battery monitor information,
identification codes, warranty information, or other
critical battery parameters during periods when the
battery is temporarily shorted or deeply discharged.
