EM6325

Reset Circuit with Manual Reset

Description

The EM6325 is an ultra-low current reset circuit available in a

large variety of configurations and very small packages for

maximum flexibility in all end-applications up to 125°C and

using power supplies between 1.5V and 5.5V.

This circuit monitors the supply voltage of any electronic

system, and generates the appropriate reset signal after a

fixed reset timeout period. The threshold defines the

minimum allowed voltage which guarantees the good

functionality of the system. When V

rises above V

, the

output remains active for an additional delay time. This

allows the system to stabilize before getting fully active.

This circuit features a Manual Reset: an input that asserts

reset when pulled low (

with internal pull-up).

Small SC70-5L and SOT23-5L packages as well as ultra-low

supply current of 2.9μA make the EM6325 an ideal choice

for portable and battery-operated devices.

Name

Function

Active-low RESET output. RESET remains low for the reset timeout period and

RESET

then goes high after all reset conditions are deasserted or after

MR goes from low

to high

Ground

Active-high RESET output. RESET remains high for the reset timeout period and

GND

RESET

then goes low after all reset conditions are deasserted or after MR goes from low to

high

Manual Reset input with an internal pull-up 15k

resistor. Reset remains active as

long as MR is low and for t

POR

after MR returns high. MR can be driven with a

CMOS output or shorted to ground with a switch
