Resets and supervisors
Portfolio overview
Run your application with carefree supervision
Reset is a mandatory function
to ensure proper wake-up of
complex systems but also
reboot in case of failing or
frozen applications. With
the democratization of
microprocessing units, there
is an ever-increasing need for
resets and supervisors.
ST’s portfolio includes:
- basic or multi-voltage resets
- single or dual pushbutton
Smart Resets™
- more advanced supervisors
with watchdog, early power-fail
detection, battery switchover
functions
