Circuit

At

power

on

When

P-ON

voltage

reaches

16V,

the

current

flows

through

the

zener

diode

(MTZ16B)

so

that

the

level

at

point

@

goes

high.

‘The

eve}

of

P-OFF

rises

as

VCC

increases.

As

a

result,

the

P-

OFF

signal

changes

from

low

to

high

level.

At

power

off

When

the

power

is

turned

off,

the

P-ON

voltage

drops

under

15V

causing

the

zener

diode

to

stop

current

flow,

which

causes

potential

at

point

@

to

drop.
