description: |
  The TPS380x family [1] of supervisory circuits monitor supply voltages to
  provide circuit initialization and timing supervision. The devices assert a
  RESET signal if the voltage drops below a preset threshold or upon a manual
  reset input (MR). The RESET output remains asserted for the factory
  programmed delay after the voltage return above its threshold or after the
  manual reset input is released.
