PT7M6714
The PT7M6709/6714 quad voltage monitors provide
accurate monitoring of up to four supplies without any
external components. A variety of factory-trimmed
threshold voltages and supply tolerance are available to
optimize the PT7M6709/6714 for specific applications.
The selection includes input options for monitoring 5.0V,
3.3V, 3.0V, 2.5V and 1.8V voltages. Additional high-
input impedance comparator options can be used as
adjustable voltage monitors, general-purpose compare-
ators, or digital-level translators.
The PT7M6709 provides four independent open-drain
outputs with 10μA internal pull-up to Vcc. The
PT7M6714 provides an active-low, open-drain RESET
output with integrated reset timing and three power-fail
comparator outputs.
Each of the monitored voltages is available with trip
thresholds to support power-supply tolerances of either
5% or 10% below the nominal voltage. An internal
bandgap reference ensures accurate trip thresholds
across the operating temperature range.
The PT7M6709 consumes only 15μA (typical) of supply
current. The PT7M6714 consumes only 20μA (typical)
of supply current. The PT7M6709/6714 operates with
supply voltages of 2.0V to 5.5V. An internal under-
voltage lockout circuit forces all four digital outputs low
when Vcc drops below the minimum operating voltage.
The four digital outputs have weak internal pull-ups to
Vcc, accommodating wire-ORed connections. Each
input threshold voltage has an independent output. The
PT7M6709/6714 are available in MSOP-10 packages
and operate over the extended (-40°C to + 85°C)
temperature range.
