8.4.3 Power-On Reset (POR)
The TLV18xx -Q1 family has an internal Power-on-Reset (POR) circuit for known start-up or power-down conditions. While the power supply (V+) is ramping up or ramping down, the POR circuitry will be activated for up to 200 μs after the minimum supply voltage threshold of 2.4 V is crossed, or immediately when the supply voltage drops below 2.4 V. 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).
For the TLV181x-Q1 push-pull output devices, the output is held low during the POR period (ton).
For the TLV182x-Q1 open drain output option the POR circuit will keep the output high impedance (Hi-Z) during the POR period (ton).
Figure 8-2 Power-On Reset Timing DiagramNote: The output voltage rises with the pull-up voltage during the POR period.
