Working Principles

The TPS2592ZADRCT operates based on a combination of voltage and current monitoring techniques. It continuously monitors the input voltage level through the OV pin and compares it with the set overvoltage threshold. If the input voltage exceeds this threshold, the device triggers the overvoltage protection mechanism, disconnecting the load from the source.

Similarly, the TPS2592ZADRCT monitors the output current through the OC pin. If the output current surpasses the set overcurrent threshold, the device activates the overcurrent protection feature, limiting the current flow to protect the load.
