... MAX16913A also feature a short-to-battery detection every time the internal switch turns on. These devices provide an active-high control input to put the devices in low-power shutdown mode. The MAX16913/MAX16913A are available in the 16-pin QSOP package and operate over the -40°C to +105°C temperature range. Remote LNA Phantom Power ...

... MAX16913A features an adjustable open-load threshold. For the MAX16913, when (V 20mV (typ), the device signals open load. For the MAX16913A, using a resistive divider between REF, the open-load threshold adjustment pin (OLT), and GND sets the open-load threshold (see the Open- Load Threshold Selection section). ...

... Short-to-Battery Detection It may happen that OUT is shorted to the battery due to a fault in the system. The MAX16913/MAX16913A detect this failure by comparing the OUT voltage and the IN voltage before the switch turns on. Every time the switch turns on, such as at the end of the retry time, or once the thermal shutdown condition disappears, the short-to-battery detection is performed ...
