• Limited availability of alternative models from other manufacturers.

Working Principles

The S-80835CNUA-B8UT2U IC operates by comparing the supply voltage with a reference level. When the voltage drops below the threshold, the internal circuitry triggers the RESET pin to go low, indicating a reset condition. The built-in delay circuit ensures that the reset signal remains active for a specific duration, allowing the system to stabilize before resuming normal operation.
