Power Supply Supervisors
Description
The CAT8801 is a supervisory circuit that monitors power supplies
in digital systems and provides a reset signal whenever the system’s
input voltage is below a prescribed minimum level. The CAT8801
replaces popular voltage supervisors such as MAX809 in applications
where operating current is a primary consideration.
CAT8801 generates a reset signal, which is asserted while the power
supply voltage is below a preset threshold level and remains asserted
for at least 140 ms after the power supply level has risen above that
level. Nine industry standard threshold levels are offered to support
+5.0 V, +3.3 V, +3.0 V, +2.5 V and +1.8 V systems. ON Semiconductor’s
floating gate technology, used in programming the trigger thresholds,
makes it possible to quickly offer any custom reset threshold value
should the 9 standard voltage thresholds not meet a system’s needs.
The CAT8801 features a PushPull CMOS RESET output (active
LOW) and is fully specified over the industrial temperature range of
40
°C to 85°C.
CAT8801 is available in compact 3pin SOT23 and SC70
packages.
