CAT885  
Five-Channel Power Supply Supervisors  
FEATURES  
DESCRIPTION  
„ Five-channel supply voltage detection  
„ 2 VDD inputs allow monitoring of  
The CAT885 is  
a
five-channel power supply  
supervisory circuit with high reset thereshold accuracy  
and very low power consumption. The device features  
an open-drain output, active-low function with manual  
reset to perform basic system reset and monitoring  
functions for a wide range of electronic products. The  
CAT885 monitors five system voltages by maintaining a  
reset output active until all the power supply voltages  
exceed the specified trip values. The device then  
maintains the reset output in an active condition until  
the internal timer times out, which allows the system  
power supplies to stabilize.  
+5.0V, +3.3V, +3.0V, +2.5V or +1.8V supplies  
„ 3 adjustable voltage inputs allow monitoring  
supplies > 0.6V  
„ 70ms minimum reset delay  
„ Manual reset capability  
„ Reset signals valid down to VDD = 1V  
„ Accurate ± < 2% voltage threshold  
„ Power-supply transients suppressed  
„ Low 2µA maximum supply current at 5V  
„ RoHS-compliant MSOP package  
Two of the five voltage detectors are factory set for  
standard supplies, while the threshold voltages of the  
third, fourth, and fifth voltage monitors can be adjusted  
for specific system design requirements using external  
resistors.  
APPLICATIONS  
„ Telecom & datacom systems  
„ Routers & servers  
„ Data storage equipment  
„ Set-top boxes  
The CAT885 lowers system costs and saves board  
space by integrating five channels into a single, small  
MSOP 8-lead package.  
„ Multi-voltage systems
