8.3.5 User-Programmable Sense Delay

TPS37 has adjustable sense release time delay with external capacitors. Channel timing are independent of each other. Sense delay is used as a de-glitcher or ignoring known transients.

  • A capacitor in CTS1 program the excursion detection on SENSE1.
  • A capacitor in CTS2 program the excursion detection on SENSE2.
  • No capacitor on these pins gives the fastest detection time indicated in the Section 7.6.
