Working Principles

The LTC2965IMS#TRPBF operates by comparing the input voltages with the user-programmed thresholds. If any voltage falls below the undervoltage threshold or exceeds the overvoltage threshold, the IC generates an active-low reset signal. The reset timeout delay can be adjusted to allow for temporary voltage fluctuations without triggering a reset.
