DESCRIPTION
The
supervisory circuits in a 5-pin SOT23 package, that combine
the functions of power supply and Processor monitoring.
SiP823/SiP824/SiP825
series
are
Processor
If the power supply voltage drops, or has been, below a safe
level or the Processor shows signs of problematic inactivity,
the circuit will generate a reset signal at it’s output.
The SiP823 and SiP825 have an input to accommodate
manual reset.
Seven pre-programmed reset threshold voltage levels are
available as standard options.
Specially configured options are available upon request,
allowing for further customization of reset voltage, reset
time-out, and watchdog time-out periods.
The SiP823 has a reset output that is “active low” and the
SiP824 and SiP825 have complementary outputs for both
“active high” and “active low” resets. Both output drives are
push/pull configurations.
Space saving SOT23-5 packages and low quiescent current
make this family of products ideally suited for portable battery
operated equipment.
These circuits fully ignore fast negative V
CC
transients and
have valid reset output signals with power supply levels down
to 1 V.
