7.4 Device Functional Modes

The TLV7081 has a power-on-reset (POR) circuit. While the power supply (VS) is greater than VPOR (typically 1V) and less than the minimum operating supply voltage, either upon ramp-up or ramp-down, the POR circuitry is activated.

The POR circuit keeps the output high impedance (logical high) while activated.

When the supply voltage is greater than, or equal to, the minimum supply voltage, the comparator output reflects the state of the input IN.
