4-Pin Microprocessor Reset Monitor

(Preliminary)

SE811

Description

Features

The SE811 is

cost-effective system

Precision V_CCMonitor for 2.8V, 3.0V, 3.3V, and

5.0V Supplies

supervisor Integrated Circuit (IC) designed to

monitor V_CCin digital and mixed signal systems and

provide a warning signal when the system power

supply is out of working range, and a reset signal to

the host processor when necessary. No external

components are required. The SE811 also provides

a manual reset input.

150mSec typical RESET Output Delay.

RESET Output Guaranteed to V_CC=1.0V

Low 7μA Supply Current typical.

V_CCTransient Immunity

Manual reset input.

4-Pin SOT-143 Package

The reset output is driven active within 20μsec

of V_CCfalling through the reset voltage threshold.

Reset is maintained active after V_CCrises above the

RESET threshold. The SE811 has an active-low

RESET output. The output of the SE809 is

guaranteed valid down to V_CC=1V.

No External Components

ESD rating is 2KV(HBM).

Wide Operating Temperature: -40°C to 125°C

100% Lead (Pb)-Free

Application

The SE811 is characterized for operation from

-40^oC to 125^oC, junction temperature. The SE811 is

optimized to reject fast transient glitches on the V_CC

line. Low supply current of 7μA (V_CC=3.3V) makes

these devices suitable for battery powered

applications. The output voltages range from 1.7V

to 4.5V in 100mV increments. Standard voltage

versions are 2.30, 2.63, 2.93, 3.08, 4.0, 4.38, and

4.63V.
