7.4.3 Known Startup Condition

The TLV3601-Q1 and TLV3603-Q1 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

reflects the state of the input pins.

Figure 7-1 shows how the TLV3601-Q1/TLV3603-Q1 output responds 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.
