Working Principles

LTC2903IS6-E1#TRMPBF operates by continuously monitoring the input voltage (VIN) and comparing it to the threshold voltage (TH). When the input voltage falls below the threshold, the output (OUT) is activated, indicating a power supply fault. The power-on reset delay ensures that the output remains inactive for a specific period after power-up to avoid false alarms.
