Description

The PT7M64xx series are µ 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

falls below the

internal V

TH-

and remains asserted until V

rises above

×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

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

+85° temperature range.
