|
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.
