CAT853, CAT863

CATCAT859,

CAT869

3-Pin Microprocessor Power Supply Supervisors

FEATURES

Precision monitoring of +3.3 V (-5%, -10%), 5 V

(-10% Power Supplies)

Active low reset output

Reset valid down to V

= 1.0 V

6 µA power supply current

Power supply transient immunity

Industrial temperature range: -40ºC to +85ºC

RoHS-compliant SOT-23 package

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

levels as low as 1.0 V.

APPLICATIONS

Computers

Servers

Laptops

Cable modems

Wireless communications

Embedded control systems

White goods

Power meters

Intelligent instruments

PDAs and handheld equipment
