General
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
VCC falls below the internal VTH- and remains asserted
until VCC rises above VTH+ (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
detectors with a propagation delay of 17s.
Table 1. Suffix “xx” definition of PT7M61xx
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.
