Description
The PT7M62xx serials of ultra-low-power voltage
detectors monitor battery, power-supply and system
voltages. Each circuit includes a precision bandgap
reference, a comparator, internally trimmed resistor
networks that set specified trip thresholds, and an
internal 5% threshold hysteresis circuit. Output is
asserted when V
CC
rises above V
TH+
(V
TH+
= V
TH-
×
1.05) and remains asserted until V
CC
falls below the
internal V
TH-
. These devices provide excellent circuit
reliability and low cost by eliminating external
components and adjustments when monitoring nominal
system voltages from +1.8V to +5V in 100mV
increments. The series are voltage detectors with a
propagation delay of 20µ
CC
rise).
s(V
The family is available with three output stage options:
push-pull with active-low output, push-pull with
active-high output, and open drain with active-low
output.

Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for extended
periods may affect reliability.
