Table 8: Temperature dependent behavior
Sending temperature alert (15s after BGS12 startup, otherwise only if URC presentation
enabled)
^SCTM_B: 1 Board close to overtemperature limit.
^SCTM_B: -1 Board close to undertemperature limit.
^SCTM_B: 0 Board back to non-critical temperature range.
Automatic shutdown (URC appears no matter whether or not presentation was enabled)
^SCTM_B: 2 Alert: Board equal or beyond overtemperature limit. BGS12 switches off.
^SCTM_B: -2 Alert: Board equal or below undertemperature limit. BGS12 switches off.
3.3.5.2
Undervoltage Shutdown
The undervoltage shutdown threshold is 3.2V, i.e., it is 50mV below the specified minimum
supply voltage V
BATT+
given in Table 21
When the average supply voltage measured by BGS12 drops below the undervoltage shut-
down threshold the module will send the following URC:
^SBC: Undervoltage
This alert is sent only once before the module shuts down cleanly without sending any further
messages.
This type of URC does not need to be activated by the user. It will be output automatically when
fault conditions occur.
3.3.5.3
Overvoltage Shutdown
The overvoltage shutdown threshold is equal to the maximum supply voltage V
BATT+
spe-
cified in Table 21.
When the supply voltage approaches the overvoltage shutdown threshold the module will send
the following URC:
^SBC: Overvoltage
This alert is sent once.
When the overvoltage shutdown threshold is exceeded the module will shut down cleanly.
This type of URC does not need to be activated by the user. It will be output automatically when
fault conditions occur.
Keep in mind that several BGS12 components are directly linked to BATT
+BB
and BATT
+RF
,
therefore, the supply voltage remains applied at major parts of BGS12. Especially the power
amplifier linked to BATT
+RF
is very sensitive to high voltage and might
even be destroyed.
