Detailed Description
The MAX6709/MAX6714 are low-power, quad voltage
monitors designed for multivoltage systems. Preset
voltage options for 5.0V, 3.3V, 3.0V, 2.5V, and 1.8V
make these quad monitors ideal for applications such
as telecommunications, desktop and notebook comput-
ers, high-end printers, data storage equipment, and
networking equipment.
The MAX6709/MAX6714 have an internally trimmed
threshold that minimizes or eliminates the need for
external components. The four open-drain outputs have
weak (10A) internal pullups to VCC, allowing them to
interface easily with other logic devices. The weak inter-
nal pullups can be overdriven by external pullups to any
voltage from 0 to 5.5V. Internal circuitry prevents current
flow from the external pullup voltage to VCC. The out-
puts can be wire-ORed for a single power-good signal.
The MAX6709 quad voltage monitor includes an accu-
rate reference, four precision comparators, and a
series of internally trimmed resistor-divider networks to
set the factory-fixed threshold options. The resistor net-
works scale the specified IN_ reset voltages to match
the internal reference/comparator voltage. Adjustable
threshold options bypass the internal resistor networks
and connect directly to one of the comparator inputs
(an external resistor-divider network is required for
threshold matching). The MAX6709 monitors power
supplies with either 5% or 10% tolerance specifica-
tions, depending on the selected version. Additional
high-input-impedance comparator options can be used
