| 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. |
