9.4.5 TLV3011B-Q1 and TLV3012B-Q1 Power On Reset

The TLV3011B-Q1 and TLV3012B-Q1 have 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 1.9ms after the minimum supply voltage threshold is crossed, or immediately when the supply voltage drops below minimum supply. 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). This delay is long enough to allow the reference output to stabilize with up to a 10nF capacitive load.

During the POR period (ton), the outputs will be the following:

  • The open drain output TLV3011B-Q1 will be high (Hi-Z).

  • The push-pull output TLV3012B-Q1 will be low (sinking).

Note that it the nature of an open collector output that the output will rise with the pull-up voltage during the HI-Z POR period.
