DESCRIPTION
The MC33164-3 and MC34164-3 are
undervoltage sensing circuits designed
specifically for use as reset controllers in
microprocessor-based systems. They
offer 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 MC33164-3 and MC34164-3
consist of a temperature stable reference
comparator with hysteresis, high-current
clamping diode and an open collector
output stage capable of sinking more
than 6mA over the full temperature
range. The MC33164-3 and MC34164-3's
RESET output is specified to be fully
functional at V
