Working Principles

The LTC2909ITS8-2.5#TRMPBF operates by comparing the input voltage with a fixed threshold value. If the input voltage exceeds the threshold, the output signal goes low, indicating an overvoltage condition. Conversely, if the input voltage falls below the threshold, the output signal goes high, indicating an undervoltage condition. The power sequencing control is achieved through the GATE pin, which enables or disables the power supplies based on the desired sequence.
