Figure 13: 5-Way Active Power Splitter with external moSFet
Note:
Pin 22 must have 3.3 V maintained, even during power loss. This is normally accomplished by a battery backup. Upon
power loss, the FET load switch (SI 1869DH) cuts off power to the five output amplifiers, and puts the APS3625 in bypass
mode.
