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.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures of 0°C ≤ TA ≤ 70°C for the MC34064 and -40°C ≤ TA ≤ 85°C
for the MC33064. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
