TYP
Output configuration: N-channel open drain or
CMOS
Reset timeout period at least 120ms
The PT7M64xx series are µP supervisory circuits with 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 35µs.
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°C to
+85°C temperature range.
