DESCRIPTIOꢀ

■ Precision monitoring of

+5.0V (-5%, -10%, -20%),

+3.3V (-5%, -10%),

The CAT803, CAT809, and CAT8ꢀ0 are supervisory

circuitsthatmonitorpowersuppliesindigitalsystems.The

CAT803, CAT809, and CAT8ꢀ0 are direct replacements

for the MAX803, MAX809 and MAX8ꢀ0 in applications

operating over the industrial temperature range.

+3.0V (-10%) and

+2.5V (-5%) power supplies

■ Offered in three output conﬁgurations:

- CAT803: Open-Drain Active LOW reset

- CAT809: Push-Pull Active LOW reset

- CAT810: Push-Pull Active HIGH reset

Thesedevicesgeneratearesetsignal,whichisasserted

while the power supply voltage is below a preset

threshold level and for at least ꢀ40 ms after the power

supply level has risen above that level. The underlying

ﬂoating gate technology, AE^2(TM)used by Catalyst

Semiconductor, makes it possible to offer any custom

resetthresholdvalue.Sevenindustrystandardthreshold

levels are offered to support +5.0V, +3.3V, +3.0V and

+2.5V systems.

■ Direct replacements for the MAX803, MAX809

and MAX810 in applications operating over the

industrial temperature range

■ ꢂeset valid down to V_CC= 1.0V

■ 6µA power supply current

The CAT803 has an open-drain RESET output (active

LOW). The CAT803 requires a pull-up resistor on the

reset output.

■ Power supply transient immunity

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

■ Available in RoHS-compliant SOT-23 and SC70

The CAT809 features a push-pull RESET output (active

LOW) and the CAT810 features a push-pull RESET

output (active HIGH).

APPLICATIOꢀS

■ Computers

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 ꢀ.0V.

■ Servers

■ Laptops
