The bq2060 polls the ALARM_MODE bit at least
every 150ms. Whenever the ALARM_MODE bit is
set, the bq2060 resets the bit and starts or restarts a
55s (nominal) timer. After the timer expires, the
bq2060 automatically enables alarm broadcasts to
ensure that the accidental deactivation of broadcasts
does not persist. An SMBus host that does not want
the bq2060 to be a master on the SMBus must
therefore continually set this bit at least once per 45s
tokeep thebq2060 from broadcasting alarms.
The ALARM_MODE bit defaults to a cleared state
within 130ms after the bq2060 detects the SMBus
Off-State.
The condition of the ALARM-MODE bit does NOT
affect the operation or state of the CHARGER_MODE

Note 1:
The following functions are changed to accept or
return values in mA/mAh or 10mW/10mWh depending
on theCAPACITY_MODE bit:
RemainingCapacityAlarm()
AtRate()
RemainingCapacity()
FullChargeCapacity()
DesignCapacity()
Note 2:
The following functions are calculated on the
basis of capacity and may be calculated differently de-
pending on theCAPACITY_MODE bit:
AtRateOK()
AtRateTimeToEmpty()
AtRateTimeToFull()
RunTimeToEmpty()
AverageTimeToEmpty()
AverageTimeToFull()
Remaining TimeAlarm()
BatteryStatus()
The bq2060 updates the non-AtRate related register val-
ues within 3s of changing the state of the CAPAC-
ITY_MODE bit. The AtRate() values will be updated af-
ter the next AtRate value is written to the bq2060 (or af-
ter thenext 20s scheduled refresh calculation).
AtRate() (0x04); [0x04]
Description:
The AtRate() function is the first half of a two-function
call-set used to set the AtRate value used in calculations
made by the A tR ateT imeToF ull(), A tR ateT ime-
ToE mpty(), and AtRateOK () functions.
value may be expressed in either current (mA) or power
(10mW) depending on the setting of the BatteryMode()’s
CAPACITY_MODE bit.
The AtRate
Purpose:
Since the AtRate() function is the first half of a
two-function call-set, it is followed by the second func-
tion of the call-set that calculates and returns a value
based on the AtRate value and the battery’s present
state.
A delay of up to 1.3s is required after writing
AtRate() before the bq2060 can acknowledge the re-
quested AtRatefunction.
When the AtRate() value is positive, the AtRate-
TimeToFull() function returns the predicted time to
full-chargeat theAtRatevalueof charge.
When
AtRateTimeToEmpty() function returns the predicted
operating timeat theAtRatevalueof discharge.
the
AtRate()
value
is
negative,
the
When the AtRate() value is negative, the AtRateOK()
function returns a Boolean value that predicts the
battery’s ability to supply the AtRate value of
additional
discharge energy (current or power) for 10
seconds.
T he default value for AtR ate() is zero.
AtRate() values over the HDQ16 serial port does NOT
trigger a re-calculation of A tR ateT imeToF ull(),
AtRateTimeToEmpty(), and AtRateOK() functions.
Writing
It is recommended that AtRate() requests should be lim-
ited toonerequest every 4s.
