Discription

The PT7M64xx series are µP supervisory circuits with a

minimum reset timeout period of 140ms. 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

and remains asserted until V

rises above V

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.
