Description
The PT7M64xx series are µ supervisory circuits with
P
a minimum reset timeout period of 120ms. Each circuit
includes a precise bandgap reference; a comparator, a
reset timeout circuit, internally trimmed resistor
networks that set specified trip thresholds, and an
internal 5% threshold hysteresis circuit (see the
Block
Diagram).
Output is asserted when V
CC
falls below the
internal V
TH-
and remains asserted until V
CC
rises above
V
TH+
(V
TH+
= V
TH-
×1.05)
after a reset timeout period.
These devices provide excellent circuit reliability and
low cost by eliminating external components and
adjustments when monitoring normal systems voltage
from +1.8V to +5V in 100mV increments. The series
are voltage detectors with a propagation delay of 35µ
s.
The family is available with four output stage options:
push-pull with active-low output, push-pull with active-
high output, open drain with active-low output and
bidirection port with active-low output and pushbutton
reset input. These devices specified over the -40° to
C
+85° temperature range.
