DESCRIPTION

The CAT811 and CAT812 are microprocessor supervisory circuits that monitor power supplies. The CAT811 and CAT812 are direct replacements for the MAX811 and MAX812 in applications operating over the industrial temperature range; both have a manual reset input.

FEATURES

■ Precision monitoring of +5.0 V (± 5, ± 10, ± 20), +3.3 V (± 5, ± 10), +3.0 V (± 10) and +2.5 V (± 5) power supplies

■ Manual reset input

■ Offered in two output configurations:

■ CAT811: Active LOW reset

■ CAT812: Active HIGH reset

■ Direct replacements for the MAX811 and MAX812 in applications operating over the industrial temperature range

■ Reset valid down to VCC = 1.0V

■ 6µA power supply current

■ Power supply transient immunity

■ Available in SOT-143 packages with Sn or NiPdAu Green Lead finishes.

■ Industrial temperature range: -40ºC to +85ºC

APPLICATION

■ Computers, Servers, Laptops

■ Cable modems

■ Wireless communications

■ Embedded control systems

■ White goods

■ Power meters

■ Intelligent instruments

■ PDAs and handheld equipment
