9 / 23 page www.SiliconStandard.com 9 of 23 SS4002AG 12/16/2005 Rev.3.01 ManufacturerAccess() (0x00) This function provides means to control the SS4002AG during normal operation and pack manufacturing. The following commands are available. 01XX Engineer support command 02XX Engineer support command 03XX Calibration command: 0404 Reset (cold start, can be sealed) 05XX LED control command: 0501: LED test 0502: Normal mode 06XX Engineer support command All the engineer support commands are used for maintenance support only. Input/Output: Set command and get return value in certain sort of commands. RemainingCapacityAlarm() (0x01) This function sets or returns the remaining capacity alarm value. When RemainingCapacity falls below the RemainingCapacityAlarm value initialized from the external EEPROM, the RemainingCapacityAlarm bit is set in BatteryStatus. The system may alter this alarm during operation. Input/Output: unsigned integer. This sets/returns the value where the RemainingCapacityAlarm bit is set in Battery Status. Units: mAh/10mWh Range: 0 to 65,535 RemainingTimeAlarm() (0x02) This function sets or returns the remaining time alarm value. When the AverageTimeToEmpty falls below the RemainingTimeAlarm value initialized from EEPROM, the Remaining_Time_Alarm bit in BatteryStatus is set. The system may alter this alarm during operation. Input/Output: unsigned integer. This sets/returns the value where the Remaining_Time_Alarm bit is set in Battery Status. Units: minutes Range: 0 to 65,535 minutes BatteryMode() (0x03) This read/write word selects the various battery operational modes. The lower byte is read-only, any input data will be no effects on the lower byte. The SS4002AG supports neither internal charge control nor primary battery support. Bit definition is shown in Table 2. Since bits 0 and 1 are 0s, bits 8 and 9 have no effect. The SS4002AG does support the battery capacity information specified in both mAhr and 10mWh modes. AtRate() (0x04) This read/write word is the first half of a two-function set used to set the AtRate value used in calculations made by the AtRateTimeToFull() and AtRateTimeToEmpty(). When the AtRate value is positive, the AtRateTimeToFull function returns the predicted time to charge full at the AtRate value of charge. When the AtRate value is negative, the AtRateTimeToEmpty function returns the predicted operating time until charge empty at the AtRate value of discharge. Input/Output: signed integer. AtRate is positive for charge and negative for discharge. Units: mA/10mW Range: -32,768 to 32,767 AtRateTimeToFull() (0x05) This read-only word returns the predicted remaining time to fully charge the battery at the AtRate value (mA). The calculation is according to the latest set of AtRate value. Output: unsigned integer. Returns the predicted time to full charge. Units: minutes Range: 0 to 65,534 Invalid Data Indication: 65,535 indicate that the AtRate is a negative value. AtRateTimeToEmpty() (0x06) This read-only word returns the predicted remaining operating time if the battery is discharged at the AtRate value. The calculation is according to latest set of AtRate value. Output: unsigned integer. Returns the predicted time to empty. Units: minutes Range: 0 to 65,534 Invalid Data Indication: 65,535 indicate that the AtRate is a positive value. AtRateOK() (0x07) This read-only word returns a Boolean value that indicates whether or not an additional load with AtRate (mA) can be provided for longer than 10 seconds. Boolean: Indicates if the battery can supply additional energy with rate of AtRate (mA) for at least 10 seconds. Units: Boolean Range: TRUE ?? 0, FALSE = 0 Temperature() (0x08) This read-only word returns the battery pack's internal temperature. Output: unsigned integer. Returns the cell temperature in tenths of degrees Kelvin increments. Units: 0.1°K Range: 0 to +500.0°K Accuracy: ? 2°K after calibration Voltage() (0x09) This read-only word returns the battery pack voltage (mV). Output: unsigned integer. Returns the battery terminal voltage in mV. Units: mV Range: 0 to 65,535mV Accuracy: ? 1% of DesignVoltage after calibration |
