Application Circuits

Microcomputer Reset Circuit

Normally a reset circuit is required to

protect the microcomputer system from

malfunctions due to power line inter-

rupttions.

The

following

examples

show how different output configure-

tions

perform

a reset function in

various systems.

NMOS open drain output application

for separate power supply

NMOS open drain output application

with R-C delay

Power-on Reset Circuit

With several external components, the

NMOS

open

drain

type

the

series can be used to

perform a power-on reset function as

shown:

5V Power Line Monitoring Circuit

Generally,

minimum

operating

voltage of 4.5V is guaranteed in a 5V

power line system. The

recommended for use as 5V power line

monitoring circuit.

5V power line monitor with power-on

reset

With 5V voltage regulator
