LTC4417 Datasheet - Linear Technology

LTC4417 Prioritized PowerPath Controller

The LTC®4417 connects one of three valid power supplies to a common output based on priority. Priority is defined by pin assignment, with V1 assigned the highest priority and V3 the lowest priority. A power supply is defined as valid when its voltage has been within its overvoltage (OV) and undervol.
