CAT8801

200 nA Microprocessor

Power Supply Supervisors

Description

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.

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.
