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鈥檚,

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.
