ALERT Signal
Chapter 8
SLUUBH1C–August 2016–Revised March 2018
ALERT Signal
The ALERT signal can be configured to be triggered by a variety of status conditions. When the ALERT
Configuration bit is set AND the corresponding bit in BatteryStatus() or ControlStatus() is set, then the
corresponding BatteryAlert() bit is set, triggering the ALERT signal.
For example: If BatteryStatus() [BATLOW] AND ALERT Configuration [BATLOW] = 1, then
BatteryAlert() [BATLOW] is set and the ALERT pin is triggered.
The ALERT signal is cleared upon a read of BatteryStatus().

BATLOW (Bit 7): Battery voltage low condition
0 = ALERT is not triggered when BATLOW becomes set (default).
1 = ALERT is triggered when BATLOW becomes set.
TEMPLOW (Bit 6): Battery temperature low condition
0 = ALERT is not triggered when TEMPLOW becomes set (default).
1 = ALERT is triggered when TEMPLOW becomes set.
TEMPHIGH (Bit 5): Battery temperature high condition
0 = ALERT is not triggered when TEMPHIGH becomes set (default).
1 = ALERT is triggered when TEMPHIGH becomes set.
SOH_LOW (Bit 4): Low SOH State detected
0 = ALERT is not triggered when SOH_LOW becomes set (default).
1 = ALERT is triggered when SOH_LOW becomes set.
EOS (Bit 3): End-Of-Service state detected
0 = ALERT is not triggered when EOS becomes set (default).
1 = ALERT is triggered when EOS becomes set.
RSVD (Bit 2): Reserved. Do not use.
G_DONE (Bit 1): Gauge Done State reached
0 = ALERT is not triggered when G_DONE becomes set (default).
1 = ALERT is triggered when G_DONE becomes set.
INITCOMP (Bit 0): Initialization Complete
0 = ALERT is not triggered when INITCOMP becomes set (default).
1 = ALERT is triggered when INITCOMP becomes set.
