Pin Configuration
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 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+ (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.
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.
