The TLV360x have a Power-on-Reset (POR) circuit which provides system designers a known start-up condition for the output of the comparators. When the power supply (VCC) is ramping up or ramping down, the POR circuit will be active when VCC is below VPOR. When active, the POR circuit holds the output low at VEE. When VCC is greater than or equal to VPOR as stated in Section 6.5 , the comparator output reflects the state of the input pins.
Figure 7-1 shows how the TLV360x outputs respond for VCC rising. The input is configured with a logic high input to highlight the transition from the POR circuit control (logic low output) to a standard comparator operation where the output reflects the input condition. Note how the output goes high when VCC reaches 2.1V.
