Description

The PT7M61xx serials of ultra -low-power voltage detectors monitor battery, power -supply and system voltages. Each circuit includes a precision b andgap reference, a comparator, internally trimmed resistor networks that set specified trip thresholds, and an internal 1% and 5% threshold hysteresis circuit. Output is asserted when V CC falls below the internal V TH- and remains asserted until V CC rises above V TH+ (VTH+ = VTH-×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 detecto rs with a propagation delay of 17µ s. 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. These devices specified over the -40° C to +85° C temperature range. Pin Configuration

VTH+is voltage threshold when Vcc rises from low to high. 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.
