10.3.5 User-Programmable Sense Delay

TPS3762-Q1 has adjustable sense release time delay with external capacitors.

  • A capacitor on CTS programs the sense time delay of the input.

  • No capacitor on this pin gives the fastest sense delay time indicated by tCTS in Section 7.7.

  • The TPS3762-Q1 comes with an optional fixed internal time delay that ignores the capacitor value at the CTS pin, check the Section 5 to verify variant specific functionality.
