    Discription
    The PT7M64xx series are P 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 VCC falls below the internal VTH-
    and remains asserted until VCC rises above VTH+ (VTH+ =
    VTH-×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 35s.
    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.
