Working Principles

The MIC6315-30D3U operates by comparing the supply voltage with the internally set threshold voltage. When the supply voltage drops below the threshold, the RESET pin is pulled low, generating a reset signal. The reset signal remains active until the supply voltage rises above the threshold and a timeout period elapses.
