Working Principles

The LTC2935IDC-4#TRPBF operates by continuously monitoring the voltages of the connected supplies. It compares these voltages with the configured undervoltage and overvoltage thresholds. If any of the monitored voltages fall below the undervoltage threshold or exceed the overvoltage threshold, the corresponding output pin goes low, indicating a fault condition. This enables the system to take appropriate actions, such as shutting down or activating backup power sources, to prevent damage or instability.
