SS809/810G

3-Pin Microprocessor Reset Circuits

FEATURES

DESCRIPTION

Ultra-low supply current 1mA (typ.)

Guaranteed reset valid to Vcc=0.9V

Available in three output types:

Open-drain active low (SS809N-xxGx)

Push-pull active low (SS809-xxGx)

Push-pull active high (SS810-xxGx)

Power-on reset pulse width min. 140ms

Internally fixed threshold 2.3V, 2.6V, 2.9V, 3.1V,

4.0V, 4.4V, 4.6V

The SS809G and SS810G are low-power microprocessor

(µP) supervisory circuits used to monitor power supplies

in µP and digital systems. They improve circuit reliability

and reduce cost by eliminating external components.

These devices provide valid signals in applications

with Vcc ranging from 6.0V down to 0.9V. The reset

signal lasts for a minimum period of 140mswhenever the

VCC supply voltage falls below a preset threshold. Both

the SS809G and SS810G were designed with a reset

comparator to help identify invalid signals lasting less

than 140ms. The only difference between the two

devices is that one has an active-low RESET output

and the other an active-high RESET output.

Tight voltage threshold tolerance: 1.5%

Packaged in RoHS-compliant SOT-23-3

APPLICATIONS

l Notebook Computers

l Digital Still Cameras

l PDAs

l Critical Microprocessor Monitoring

Low supply current (1mA) makes the SS809G and SS810G

ideal for portable equipment. The devices are available in

a SOT-23-3 package.
