description

The bq2019 advanced battery-monitoring IC accurately measures the charge and discharge currents in a

rechargeable battery pack. In pack integration, the bq2019 is the basis of a comprehensive battery-capacity

management system in portable applications such as cellular phones, PDAs, or other portable products.

The bq2019 works with the host controller in the portable system to implement the battery management system.

The host controller interprets the bq2019 data and communicates meaningful battery data to the end-user or

power-management system.

The bq2019 provides 64 bytes of general-purpose flash memory, 8 bytes of ID ROM, and 32 bytes of

flash-backed RAM for data storage. The nonvolatile memory can maintain formatted battery-monitor

information, identification codes, warranty information, or other critical battery parameters when the battery is

temporarily shorted or deeply discharged.
