11 / 75 page  www.ti.com Discharge and Charge Alarms bq20z80-V101 SLUS625D – SEPTEMBER 2004 – REVISED OCTOBER 2005 Temperature If SBS.Temperature( ) is outside of the range 10 °C to 40°C Delta Capacity If the capacity change between suitable battery rest periods is less than 37% Voltage If and SBS.CellVoltage1..4( ) is within the range of 3737mV and 3800mV The bq20z80 enables SBS.BatteryStatus( ) [TDA, FD, TCA, FC] flags to be set or cleared on the following thresholds based on SBS.RelativeStateOfCharge( ). DF:Operation Cfg A CONDITION SBS.BatteryStatus( ) FLAG ACTION [DMODE] = 0 [DMODE] = 1 ≤ DF:TDA Set % Terminate_Discharge_Alarm is set ≥ DF:TDA Clear % Terminate_discharge_Alarm is cleared ≤ DF:FD Set % Fully_Discharged is set ≥ DF:FD Clear % Fully_Discharged is cleared SBS.RelativeStateOfCharge( ) SBS.AbsoluteOfCharge( ) ≥ DF:TCA Set % Terminate_Charge_Alarm is set ≤ DF:TCA Clear % Terminate_Charge_Alarm is cleared ≥ DF:FC Set % Fully_Charged is set ≤ DF:FC Clear % Fully_Charged is cleared The SBS.RelativeStateOfCharge( ) or SBS.AbsoluteStateOfCharge( ) based thresholds can be disabled by setting the value to -1%. The SBS.BatteryStatus( ) [TDA, FD] flags can also be set or cleared based on the level of SBS.Voltage( ). If the voltage settings are not used then they should be set to extreme range values. CONDITION SBS.BatteryStatus( ) FLAG ACTION ≤ DF:TDA Volt Threshold for a period of DF:TDA Volt Time Terminate_Discharge_Alarm is set ≥ DF:TDA Recovery Terminate_discharge_Alarm is cleared SBS.Voltage( ) ≤ DF:FD Volt Threshold for a period of DF:FD Volt Time Fully_Discharged is set ≥ DF:FD Recovery Fully_Discharged is cleared See the Charge Termination and Protection sections of this data sheet for further details on the setting of Terminate_Charge_Alarm. VALID SIZE DEFAULT NAME CLASS / SUBCLASS FORMAT UNITS RANGE (BYTES) VALUE TDA Set %(1) 6 TDA Clear%(1) 8 FD Set %(1) 2 FD Clear %(1) 5 Integer -1 to 100 1 % TCA Set %(1) -1 TCA Clear %(1) 95 FC Set %(1) -1 SBS Configuration / Config (49) FC Clear %(1) 98 TDA Volt Threshold 0 to 16000 2 mV 5000 TDA Volt Time 0 to 60 1 s 5 TDA Recovery 0 to 16000 2 mV 5500 Integer FD Volt Threshold 0 to 16000 2 mV 5000 FD Volt Time 0 to 60 1 s 5 FD Recovery 0 to 16000 2 mV 5000 (1) Setting to –1% prevents the TDA, TCA, FD, or FC flag from being set or cleared based on state of charge. 11 |
