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