Application Circuits
Microcomputer reset circuit
Normally a reset circuit is required to protect the micro-
computer system from malfunctions due to power line
interruptions. The following examples show how differ-
ent output configurations perform a reset function in var-
ious 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 of the HT70XX series can be used to perform
a power-on reset function as shown:
