Output configuration: N-channel open drain or CMOS
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° to +85° temperature range.
