12description: |
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.
