CM3400

Micropower, Universal Supply Voltage Supervisor (SVS)

Product Description

Features

•

Temperature stable 1.0V trigger reference

The CM3400 is a universal supply voltage supervisory

(SVS) controller for critical power monitoring and power

sequencing applications. During an initial power-up,

both complimentary outputs (RESET, RESET) remain

active. Once the supply voltage being monitored

exceeds the user programmed reset threshold, the out-

puts will remain active for an additional timeout interval

which is also user controlled. Both outputs become

inactive once the delay interval has expired.

User adjustable reset threshold

User adjustable reset delay time > 25msec

Complimentary outputs (RESET, RESET)

Integrated pull-up/down resistors

Manual reset (MR) control input

Low operating current (40µA typ.)

8-lead MSOP and SOIC package

The user controlled reset threshold is determined by

two external resistors as follows:

Applications

•

Critical power monitoring

Power-up sequencing

Memory integrity during "brownouts"

Reset Threshold [V] = (R + R ) / R

1 2 2

The delay time is set by an external capacitor C , as

follows (where C is in [nF]):

Reset Delay [ms] = (375 x C [nF]) + 25 [ms]

During a brown-out condition, both outputs will immedi-

ately become active and remain active until the supply

being monitored has been restored for a period

exceeding the delay pulse. During a complete power-

down situation, both outputs will continually "hug" their

respective rails. This is achieved by the use of inte-

grated pull-up/down resistors.

The CM3400 is available in a low profile MSOP-8 and a

SOIC-8 package.
