6.4.5 Power-On Reset (POR)

The TLV321x devices have an internal Power-on-Reset (POR) circuit for known start-up conditions. While the power supply (V+) is ramping up, the POR circuitry is activated for up to 32us after the VPOR of 1.65V is crossed. When the supply voltage is equal to or greater than the minimum supply voltage, and after the delay period, the comparator output reflects the state of the differential input (VID).

The output is held low during the POR period (ton). This is true for both the Open-Drain and Push-Pull output options.
