Working Principles

The LTC2963IUDC-1#PBF operates by continuously monitoring the input voltage and comparing it to a precise threshold level set by the TH pin. If the input voltage falls below the threshold, the reset output is activated, indicating a power failure or fault condition. The reset timeout delay can be adjusted using an external capacitor connected to the CT pin. This delay ensures that the reset signal remains active for a specific duration after the input voltage returns to normal.
