operating principles
The LTC4365/LTC4365-1 monitors the input rail voltage
and disconnects downstream circuits when the input volt-
age is too low, too high or negative. The LTC4365 provides
accurate overvoltage and undervoltage comparators to
ensure that power is applied to the system only if the input
supply is within the allowable voltage window. Reverse
supply protection circuit automatically isolates the load
from negative input voltages.
During normal operation, a high voltage charge pump
enhances the gate of external N-channel power MOSFETs.
The controller consumes 10µA during shutdown and
125µA while operating.
