6.3 Active Antenna Supervisor - Short Circuit Protection
This is a built-in function that is monitored by the BaseBand processor. If an
abnormal current occurs and is detected, the voltage supply at pin VANT (from the
external or internal power supply) will be turned off by the BaseBand processor. The
way to reset the operation of the module is to have a hardware reset of the module,
such as turning off and then on the module or pressing the reset button.
NOTE: Without the short circuit protection, the large current will cause the damage
on the module permanently.
