3-Pin Microprocessor Reset Monitor

(Preliminary)

SE810

Description

Features

The SE810 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 VCC in 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.

150mSec typical RESET Output Delay.

Low 7μA Supply Current typical.

V_CCTransient Immunity

Small SOT-23 Package and TO-92 Package

No External Components

The reset output is driven active within 20μsec

of VCC falling through the reset voltage threshold.

Reset is maintained active for a 150mSec(typ) after

VCC rises above the reset threshold. The SE810

has an active-high RESET output.

ESD rating is 7KV(HBM).

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

100% Lead (Pb)-Free

The SE810 is characterized for operation from

-40oC to 125oC, junction temperature. The SE810

is optimized to reject fast transient glitches on the

VCC 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.
