MAX6895–MAX6899
Ultra-Small, Adjustable Sequencing/
Supervisory Circuits
General Description
The MAX6895–MAX6899 is a family of small, low-power,
voltage-monitoring circuits with sequencing capability.
These miniature devices offer tremendous flexibility with
an adjustable threshold capable of monitoring down to
0.5V and an external capacitor-adjustable time delay.
These devices are ideal for use in power-supply sequenc-
ing, reset sequencing, and power-switching applications.
Multiple devices can be cascaded for complex sequenc-
ing applications.
A high-impedance input with a 0.5V threshold allows an
external resistive divider to set the monitored threshold.
The output asserts (OUT = high or
OUT
= low) when
the input voltage rises above the 0.5V threshold and
the enable input is asserted (ENABLE = high or
ENABLE
= low). When the voltage at the input falls
below 0.5V or when the enable input is deassert-
ed (ENABLE = low or
ENABLE
= high), the output
deasserts (OUT = low or
OUT
= high). All devices pro-
vide a capacitor-programmable delay time from when
the input rises above 0.5V to when the output is assert-
ed. The MAX689_A versions provide the same capaci-
tor-adjustable delay from when enable is asserted to
when the output asserts. The MAX689_P devices have
a 1µs propagation delay from when enable is asserted
to when the output asserts.
The MAX6895A/P offers an active-high enable input
and an active-high push-pull output. The MAX6896A/P
offers an active-low enable input and an active-low
push-pull output. The MAX6897A/P offers an active-
high enable input and an active-high open-drain out-
put. Finally, the MAX6898A/P offers an active-low
enable input and an active-low open-drain output. The
MAX6899A/P offers an active-low enable with an active-
high push-pull output.
All devices operate from a 1.5V to 5.5V supply voltage
and are fully specified over the -40°C to +125°C oper-
ating temperature range. These devices are available in
ultra-small 6-pin µDFN (1.0mm x 1.5mm) and thin SOT23
(1.60mm x 2.90mm) packages.
