CAT884
Quad Voltage Supervisor
Description
The CAT884 is a four−channel power supply supervisory circuit
with high accuracy reset thresholds and very low power consumption.
The device features an active−low open−drain output with manual
reset to perform basic system reset and voltage monitoring functions
for a wide range of electronic products.
CAT884 monitors four system voltages maintaining its reset output
active until all the power supply voltages exceed the specified
threshold values. The four threshold voltages are user controlled and
can be set for system specific requirements over a range of 0.635 V to
5.5 V using external resistor dividers.
The CAT884 lowers system costs and saves board space by
integrating four channels into a single, small SOIC 8−lead package
and operates over the industrial temperature range of −40°C to +85°C.
Features
• Quad Voltage Monitoring
• Adjustable Threshold Voltages down to 0.635 V with ±2% Accuracy

• Operating Temperature Range: −40°C to +85°C
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
Applications
• Monitoring of Multiple Power Supply Voltages in mP Based Systems
