8.3.3.3 Active-High (RESET)

RESET (active-high), denoted with no bar above the pin label. RESET remains low (VOL, deasserted) as long as sense voltage is in normal operation within the threshold boundaries and VDD voltage is above UVLO. To assert a reset sense pins needs to meet the condition below:

  • For undervoltage variant the SENSE voltage need to cross the lower boundary (VITN).
  • For overvoltage variant the SENSE voltage needs to cross the upper boundary (VITP).
