3 Implementation Results

Test results are shown below for TPS7H3024-SP for the following features:

  1. Enable and disable
  2. Undervoltage and overvoltage sensing (MODE=0)
  3. Window and overvoltage sensing (MODE=1)
  4. WDOb behavior

Keep in mind that the timing of the outputs will differ slightly between TPS7H30x4-SP (push-pull variants) and TPS7H31x4-SP (open-drain variants) due in part to differences in resistance between the push-pull outputs and the external pull-up resistors as well as capacitance or other loading that may be present externally.
