MC33064/MC34064
UNDERVOLTAGE SENSING CIRCUIT
PRODUCTION DATA SHEET
DESCRIPTION
The MC34064 is an undervoltage
sensing circuit designed specifically for
use as a reset controller in microproces-
sor-based systems. It offers the designer
an economical, space-efficient solution
for low supply voltage detection when
used in combination with a single pull-
up resistor. Adding one capacitor offers
the functionality of a programmable
delay time after power returns. The
34064 consists of a temperature stable
reference comparator with hysteresis,
high-current clamping diode and open
collector output stage capable of
sinking up to 60mA. The MC34064's
RESET output is specified to be fully
functional at VIN=1V. A major improve-
ment over competing products is the
glitch-free supply current during
undervoltage detection. Competing
products demand a step function
increase in operating current during the
time that you least want or need it....
during power loss. See Product
Highlight below.
