3.2.5.2 Undervoltage Shutdown
The undervoltage shutdown threshold is the specified minimum supply voltage VBATT+ given
in Table 3. When the average supply voltage measured by PLSx3 approaches the undervolt-
age shutdown threshold (i.e., 0.05V offset) the module will send the following URC:
^SBC: Undervoltage Shutdown
If the undervoltage persists the module will send the URC several times before switching off
automatically.
This type of URC does not need to be activated by the user. It will be output automatically when
fault conditions occur.
3.2.5.3 Overvoltage Shutdown
The overvoltage shutdown threshold is the specified maximum supply voltage VBATT+ given
in Table 3. When the supply voltage approaches the overvoltage shutdown threshold, the mod-
ule will send the following URC:
^SBC: Overvoltage Shutdown
The overvoltage warning is sent only once before the module is close to the overvoltage shut-
down threshold again.
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 PLSx3 components are directly linked to BATT+ and, therefore, the
supply voltage remains applied at major parts of PLSx3, even if the module is switched off. Es-
pecially the power amplifier is very sensitive to high voltage and might even be destroyed
