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

rises above V

TH+

= V

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

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.
