FLASH-Based Precision Multi-Chemistry Charge/Discharge Counter W/High-Speed 1-Wire I/F (HDQ)
Ideal for Single-Cell Li-Ion or 3-Cell NiMHApplications High-Accuracy Coulometric Charge and
Discharge Current Integration With Offset
Calibration 32 Bytes of General-Purpose RAM 96 Bytes of Flash (Including 32 Bytes of
Shadow Flash) 8 Bytes of ID ROM Internal Temperature Sensor Eliminates the
Need for an External Thermistor
– Sleep: <1.5 μA Single-Wire HDQ Serial Interface Packaging: 8-Lead TSSOP
descriptionThe 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.
AVAILABLE OPTIONSPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
