20 / 60 page  bq28z560-R1 SLUSBD3 – APRIL 2013 www.ti.com DATA COMMANDS STANDARD DATA COMMANDS The bq28z560-R1 uses a series of 2-byte standard commands to enable system reading and writing of battery information. Each standard command has an associated command-code pair, as indicated in Table 3. Each protocol has specific means to access the data at each Command Code. DataRAM is updated and read by the gauge only once per second. Standard commands are accessible in normal operation mode. Table 3. Standard Commands SEALED NAME COMMAND CODE UNITS ACCESS Control() CNTL 0x00 / 0x01 N/A R/W AtRate() AR 0x02 / 0x03 mA R/W AtRateTimeToEmpty() ARTTE 0x04 / 0x05 Minutes R Temperature() TEMP 0x06 / 0x07 0.1K R Voltage() VOLT 0x08 / 0x09 mV R Flags() FLAGS 0x0a / 0x0b N/A R NominalAvailableCapacity() NAC 0x0c / 0x0d mAh R FullAvailableCapacity() FAC 0x0e / 0x0f mAh R RemainingCapacity() RM 0x10 / 0x11 mAh R FullChargeCapacity() FCC 0x12 / 0x13 mAh R AverageCurrent() AI 0x14 / 0x15 mA R TimeToEmpty() TTE 0x16 / 0x17 Minutes R TimeToFull() TTF 0x18 / 0x19 Minutes R StandbyCurrent() SI 0x1a / 0x1b mA R StandbyTimeToEmpty() STTE 0x1c / 0x1d Minutes R MaxLoadCurrent() MLI 0x1e / 0x1f mA R MaxLoadTimeToEmpty() MLTTE 0x20 / 0x21 Minutes R mWhr / AvailableEnergy() AE 0x22 / 0x23 R cWhr AveragePower() AP 0x24 / 0x25 mW / cW R TTEatConstantPower() TTECP 0x26 / 0x27 Minutes R Internal_Temp() INTTEMP 0x28 / 0x29 0.1°K R CycleCount() CC 0x2a / 0x2b Counts R StateOfCharge() SOC 0x2c / 0x2d % R StateOfHealth() SOH 0x2e / 0x2f % / num R PassedCharge() PCHG 0x34 / 0x35 mAh R DOD0() DOD0 0x36 / 0x37 HEX# R SelfDischargeCurrent() SDSG 0x38 / 0x39 mA R Control(): 0x00/0x01 Issuing a Control() command requires a subsequent 2-byte subcommand. These additional bytes specify the particular control function desired. The Control() command allows the system to control specific features of the bq28z560-R1 during normal operation and additional features when the bq28z560-R1 is in different access modes, as described in Table 4. Table 4. Control() Subcommands SEALED CNTL FUNCTION CNTL DATA DESCRIPTION ACCESS CONTROL_STATUS 0x0000 Yes Reports the status of DF Checksum, Hibernate, IT, etc. DEVICE_TYPE 0x0001 Yes Reports the device type of 0x0541 (indicating bq28z560-R1) 20 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: bq28z560-R1 |
