Working Principles

LTC4226CMS-2#TRPBF operates by monitoring the input voltage and comparing it to the adjustable overvoltage and undervoltage thresholds. If the voltage exceeds the overvoltage threshold, the corresponding fault indicator output is activated, and the gate control for that channel is turned off to protect downstream components. Similarly, if the voltage falls below the undervoltage threshold, the respective fault indicator output is triggered, and the gate control is disabled. The fault detection timeout can be adjusted to allow for temporary voltage fluctuations without triggering a fault condition.
