Except for the TLC7701, which can be customized with two external resistors, each supervisor has a fixed sense

threshold voltage set by an internal voltage divider. When SENSE voltage drops below the threshold voltage, the

outputs become active and stay in that state until SENSE voltage returns above threshold voltage and the delay
