Working Principles

The MAX6389XS29D3+T operates by continuously monitoring the voltage level at the VCC pin. When the voltage falls below the selected threshold voltage (determined by the TH pin), the RESET pin is asserted, generating a reset signal. The reset signal remains active until the voltage rises above the threshold voltage or the reset timeout period elapses.
