CAT811, CAT812

4-Pin Microprocessor

Power Supply Supervisors

with Manual Reset

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.

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. The

underlying floating gate technology, Analog EEPROM used by

ON Semiconductor, makes it possible to offer any custom reset

threshold value. Seven industry standard threshold levels are offered

to support +5.0 V, +3.3 V, +3.0 V and +2.5 V systems.

BI SUFFIX

CASE 527AF

The CAT811 features a RESET push−pull output (active LOW) and

the CAT812 features a RESET push−pull output (active HIGH).

Fast transients on the power supply are ignored and the output is

guaranteed to be in the correct state at Vcc levels as low as 1.0 V.

The CAT811/812 are fully specified over the industrial temperature

range (−40°C to 85°C) and are available in a compact 4−pin SOT−143

package.
