LTC44xx Monolithic PowerPath™ Prioritizers Analog Devices Inc. LTC44xx Monolithic PowerPath™ Prioritizers feature a low operating current to provide a backup switchover for keeping circuitry alive during power loss conditions. The Analog Devices LTC44xx selects the highest priority valid supply from two inputs. Unlike diode-OR products, little current is drawn from the inactive supply even if its voltage is greater than the active supply.
