Power Supply Supervisors
Description
The CAT853, CAT863, CAT859, and CAT869 are supervisory
circuits that monitor power supplies in digital systems.
These devices generate a reset signal, which is asserted while the
power supply voltage is below a preset threshold level and for at least
140 ms after the power supply level has risen above that level.
Industry standard threshold levels are offered to support +3.3 V or
5.0 V systems.
The CAT859 and CAT869 feature a RESET
push−pull output
(active low) for the two pinout options.
The CAT853 and CAT863 feature an open drain RESET
output
(active low). Both require a pull−up resistor on the RESET output.
Fast transients on the power supply are ignored and the output is
guaranteed to be in the correct state at V
CC
levels as low as 1.0 V.
Features
• Precision Monitoring of +3.3 V (−5%, −10%),
5 V (−10% Power Supplies)
• Active Low Reset Output
• Reset Valid down to V
CC
= 1.0 V
• 6 mA Power Supply Current
• Power Supply Transient Immunity
• Industrial Temperature Range: −40°C to +85°C
• SOT−23 Package
• These Devices are Pb−Free and are RoHS Compliant
Applications
• Computers, Servers, Laptops and Cable Modems
• Wireless Communications
• Embedded Control Systems
• White Goods
• Power Meters
• Intelligent Instruments
• PDAs and Handheld Equipment
