HM70 series

Low Power Voltage Detector

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

HM70XXPR

5V Power Line Monitoring Circuit

Generally, minimum operating

NMOS open drain output application

with R-C delay

voltage of 4.5V is guaranteed in a 5V

power line system. The HM61 is

recommended for use as 5V power line

monitoring circuit.

HM70XXPR

5V power line monitor with power-on

reset

Power-on Reset Circuit

With several external components, the

NMOS open drain type of the

HM61 series can be used to

perform a power-on reset function as

shown:
