Application Circuits
Microcomputer reset circuit
Normally a reset circuit is required to protect
the microcomputer system from malfunctions
due to power line interruptions. The following
examples show how different output configura-
tions perform a reset function in various sys-
tems.
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 of the HT70XX series can be
used to perform a power-on reset function as
shown:
