8.3.3.4 Active-Low (RESET)

RESET (active low) denoted with a bar above the pin label. RESET remains high voltage (VOH, deasserted) (open-drain variant VOH is measured against the pullup voltage) 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).
