FEATURES

DESCRIPTION

Multifunction Monitoring Integrated Circuit

Designed to Work With an Intelligent Host

Controller :

− Provides State of Charge Information for

Rechargeable Batteries

The bq26220 is an advanced battery monitoring

device designed to accurately measure the

charge and discharge currents in rechargeable

battery packs. Intended for pack integration, the

bq26220 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.

− Provides Accurate Battery Voltage and

Temperature Measurement

High Accuracy Coulometric Charge and

Discharge Current Integration With

Automatic Offset Compensation

The bq26220 works with the host controller in the

portable system to implement the battery

management system. The host controller is

responsible for interpreting the bq26220 data and

communicating meaningful battery data to the

end-user or power management system.

11-Bit Analog-to-Digital Converter Reports

Battery Voltage With Gain and Offset

Correction

Differential Current Sense

32 Bytes of General Purpose RAM

96 Bytes of Flash (Including 32 Bytes of

Shadow Flash)

This device 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 during periods when the battery is

temporarily shorted or deeply discharged.

8 Bytes of ID ROM

Internal Temperature Sensor Eliminates the

Need for an External Thermistor

Programmable Digital Input/Output Port

High-Accuracy Internal Timebase Eliminates

External Crystal Oscillator

Low Power Consumption:

− Operating : 30 µA

− Sleep: 1 µA

− Hibernate: 600 nA

Single-Wire HDQ Serial Interface

Packaging: 8-LEAD TSSOP
