1 Description
The STM1001 microprocessor reset circuit is a low-power supervisory device used to
monitor power supplies. It performs a single function: asserting a reset signal whenever the
V
CC
supply voltage drops below a preset value and keeping it asserted until V
CC
has risen
above the preset threshold for a minimum period of time (t
rec
).
