CAT809, CAT810

3-Pin Microprocessor Power Supply Supervisors

FEATURES

DESCRIPTION

ꢀ Precision monitoring of

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

+3.3 V ( 5%, 10%),

The CAT809 and CAT810 are µP supervisory circuits

that monitor power supplies in digital systems. The

CAT809 and CAT810 are direct replacements for the

MAX809andMAX810inapplicationsoperatingoverthe

industrial temperature range.

+3.0 V ( 10%) and

+2.5 V ( 5%) power supplies

ꢀ Offered in two output configurations:

- CAT809: Active LOW reset

Thesedevicesgeneratearesetsignal,whichisasserted

whilethepowersupplyvoltageisbelowapresetthreshold

level and for at least 140 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 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.

- CAT810: Active HIGH reset

ꢀ Direct replacements for the MAX809 and

MAX810 in applications operating over the

industrial temperature range

ꢀ Reset valid down to V = 1.0 V

CC

ꢀ 6 µA power supply current

ꢀ Power supply transient immunity

The CAT809 features a RESET push-pull output (active

LOW) and the CAT810 features a RESET push-pull

output (active HIGH).

ꢀ Available in SOT-23 and SC70 packages with

Sn or NiPdAu GREEN lead finish

ꢀ Industrial temperature range: -40°C to +85°C

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.

APPLICATIONS

ꢀ Computers

The CAT809/810 are fully specified over the industrial

temperature range (-40°C to 85°C) and are available in

compact 3-pin SOT23 and SC70 packages.

TRANSIENT RESPONSE

The CAT809/810 protect µPs against brownout failure.

Short duration transients of 4µsec or less and 100 mV

amplitude typically do not cause a false RESET.

As the amplitude of the transient goes further below the

threshold (increasing V_TH- V_CC), the maximum pulse

duration decreases. In this test, the V_CCstarts from an

initial voltage of 0.5V above the threshold and drops

CC

To ensure that the CAT809 RESET pin is in a known

state when V_CCis under 1.0 V, a 100 kΩ pull-down

resistorbetweenRESETpinandGNDisrecommended;

the value is not critical. For the CAT810, a pull-up

resistor from RESET pin to V_CCis needed.
