Description

The PT7M61xx 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

falls below the internal V

TH-

and remains asserted

until V

rises above V

TH+

= V

TH-

×1.05).

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 17µs.

Note 1:

“xx” refer to voltage range, see below table 1.

Note 2:

Lead free package is available by adding “E” after

each part no. For example: PT7M61xxCLTA3E is lead

free package part no for

PT7M61xxCLTA3.
