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
sequencing, reset sequencing, and power-switching
applications. Multiple devices can be cascaded for
complex sequencing 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 active-low OUT = low) when
the input voltage rises above the 0.5V threshold and the
enable input is asserted (ENABLE = high or active-low ENABLE =
low). When the voltage at the input falls below 0.5V or
when the enable input is deasserted (ENABLE = low or
active-low ENABLE = high), the output deasserts (OUT = low or
active-low OUT = high). All devices provide a capacitor-programmable
delay time from when the input rises above 0.5V
to when the output is asserted. The MAX689_A versions
provide the same capacitor-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 output.
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 operating
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.
