General Description
The MAX6895–MAX6899 is a family of small, low-pow-
er, voltage-monitoring circuits with sequencing
capability. These miniature devices offer tremendous
flexibility with an adjustable threshold capable of monitor-
ing 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 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
provide 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 volt-
age 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.

MAX6895–MAX6899 Ultra-Small, Adjustable Sequencing/
Supervisory Circuits
Pin Description
Detailed Description
The MAX6895–MAX6899 is a family of ultra-small, low-
power, sequencing/supervisory circuits. These devices
provide adjustable voltage monitoring for inputs down to
0.5V. They are ideal for use in power-supply sequenc-
ing, reset sequencing, and power-switching applica-
tions. Multiple devices can be cascaded for complex
sequencing applications.
Voltage monitoring is performed through a high-imped-
ance input (IN) with an internally fixed 0.5V threshold.
When the voltage at IN falls below 0.5V or when the
enable input is deasserted (ENABLE = low or ENABLE =
high), the output deasserts (OUT goes low or OUT goes
high). When VIN rises above 0.5V and the enable input is
asserted (ENABLE = high or ENABLE = low), the output
asserts (OUT goes high or OUT goes low) after a capaci-
tor-programmable time delay.
With VIN above 0.5V, the enable input can be used to
turn the output on or off. After the enable input is assert-
ed, the output turns on with a capacitor-programmable
delay period (A version) or with a 150ns propagation
delay (P version). Tables 1, 2, and 3 detail the out-
put state depending on the various input and enable
conditions.
Supply Input (VCC)
The device operates with a VCC supply voltage from
1.5V to 5.5V. To maintain a 1.8% accurate threshold,
VCC must be above 1.5V. When VCC falls below the
UVLO threshold, the output deasserts. When VCC falls
below 1.2V the output state cannot be determined. For
noisy systems, connect a 0.1µF ceramic capacitor from
VCC to GND as close to the device as possible. For the
push-pull active-high output option, a 100kΩ external
pulldown resistor to ground ensures the correct logic
state for VCC down to 0.

MAX6895–MAX6899 Ultra-Small, Adjustable Sequencing/
Supervisory Circuits
Monitor Input (IN)
Connect the center point of a resistive divider to IN to
monitor external voltages (see R1 and R2 of the Typical
Operating Circuit). IN has a rising threshold of VTH =
0.5V and a falling threshold of 0.495V (5mV hysteresis).
When VIN rises above VTH and ENABLE is high (or
ENABLE is low) OUT goes high (OUT goes low) after
the programmed tDELAY period. When VIN falls below
0.495V, OUT goes low (OUT goes high) after a 16µs
delay. IN has a maximum input current of 15nA so
large-value resistors are permitted without adding sig-
nificant error to the resistive divider.
Adjustable Delay (CDELAY)
When VIN rises above VTH with ENABLE high (ENABLE
low), the internal 250nA current source begins charging
an external capacitor connected from CDELAY to GND.
When the voltage at CDELAY reaches 1V, the output
asserts (OUT goes high or OUT goes low). When the
output asserts, CCDELAY is immediately discharged.
Adjust the delay (tDELAY) from when VIN rises above
VTH (with ENABLE high or ENABLE low) to OUT going
high (OUT going low) according to the equation:
tDELAY = CCDELAY x 4.0 x 106 + 40µs
where CCDELAY is the external capacitor from CDELAY
to GND.
For adjustable delay devices (A version), when VIN >
0.5V and ENABLE goes from low to high (ENABLE
goes from high to low) the output asserts after a tDELAY
period. For nonadjustable delay devices (P version)
there is a 1µs propagation delay from when the enable
input is asserted to when the output asserts. Figures 2
through 5 show the timing diagrams for the adjustable and
fixed delay versions, respectively.

MAX6895–MAX6899 Ultra-Small, Adjustable Sequencing/

Enable Input (ENABLE or ENABLE)
The MAX6895/MAX6897 offer an active-high enable input
(ENABLE), while the MAX6896/MAX6898/MAX6899 offer
an active-low enable input (ENABLE). With VIN above
VTH, drive ENABLE high (ENABLE low) to force OUT high
(OUT low) after the adjustable delay time (A versions).
For P version devices, when VIN > 0.5V and enable is
asserted, the output asserts after typically 150ns.
The enable input has logic-high and logic-low voltage
thresholds of 1.4V and 0.4V, respectively. For both ver-
sions, when VIN > 0.5V, drive ENABLE low (ENABLE
high) to force OUT low (OUT high) within 150ns typ.
Output (OUT or OUT)
The MAX6895/MAX6899 offer an active-high, push-pull
output (OUT), and the MAX6896 offers an active-low
push-pull output (OUT). The MAX6897 offers an active-
high open-drain output (OUT), and the MAX6898 offers
an active-low open-drain output (OUT).
Push-pull output devices are referenced to VCC. Open-
drain outputs can be pulled up to 28V.
Applications Information
Input Threshold
The MAX6895–MAX6899 monitor the voltage on IN
with an external resistive divider (see R1 and R2 in the
Typical Operating Circuit). Connect R1 and R2 as close
to IN as possible. R1 and R2 can have very high values
to minimize current consumption due to low IN leakage
currents (±15nA max). Set R2 to some conveniently high
value (1MΩ, for example) and calculate R1 based on the
desired monitored voltage using the following formula:

Pullup Resistor Values
(MAX6897/MAX6898)
The exact value of the pullup resistors for the open-drain
outputs is not critical, but some consideration should be
made to ensure the proper logic levels when the device
is sinking current. For example, if VCC = 2.25V and the
pullup voltage is 28V, you would try to keep the sink current
less than 0.5mA as shown in the Electrical Characteristics
table. As a result, the pullup resistor should be greater
than 56kΩ. For a 12V pullup, the resistor should be larger
than 24kΩ. It should be noted that the ability to sink cur-
rent is dependent on the VCC supply voltage.
Typical Application Circuits
Figures 8, 9, 10 show typical applications for the
MAX6895–MAX6899. Figure 8 shows the MAX6895
used with a p-channel MOSFET in an overvoltage pro-
tection circuit. Figure 9 shows the MAX6895 in a low-
voltage sequencing application using an n-channel
MOSFET. Figure 10 shows the MAX6895 used in a mul-
tiple-output sequencing application.
Using an n-Channel Device for Sequencing
In higher power applications, using an n-channel device
reduces the loss across the MOSFETs as it offers a
lower drain-to-source on-resistance. However, an n-
channel MOSFET requires a sufficient VGS voltage to
fully enhance it for a low RDS_ON. The application in
Figure 9 shows the MAX6895 in a switch sequencing
application using an n-channel MOSFET.
Similarly, if a higher voltage is present in the system, the
open-drain version can be used in the same manner.
