General Description
The MAX16052/MAX16053 are a family of small, low-power,
high-voltage monitoring circuits with sequencing capability.
These miniature devices offer very wide flexibility with an
adjustable voltage threshold 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 (IN) with a 0.5V threshold
allows an external resistive-divider to set the monitored
threshold. The output (OUT) asserts high when the input
voltage rises above the 0.5V threshold and the enable
input (EN) is asserted high. When the voltage at IN falls
below 0.495V or when the enable input is de-asserted
(EN = low), the output deasserts (OUT = low). The
devices provide a capacitor programmable delay time
from when the voltage at IN rises above 0.5V to when the
output is asserted.
The MAX16052 offers an active-high open-drain out-
put while the MAX16053 offers an active-high push-
pull output. Both devices operate from a 2.25V to 28V
supply voltage and feature an active-high enable input.
The MAX16052/MAX16053 are available in a tiny 6-pin
SOT23 package and are fully specified over the automo-
tive temperature range (-40°C to +125°C).

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
Electrical Characteristics
(VCC = 2.25V to 28V, VEN = VCC, TA = TJ = -40°C to +125°C, unless otherwise specified. Typical values are at VCC = 3.3V and
TA = +25°C.) (Note 1)
Note 1: All devices are production tested at TA = +25°C. Limits over temperature are guaranteed by design.
Note 2: When VCC falls below the UVLO threshold, the outputs deassert (OUT goes low). When VCC falls below 1.2V, the output
state cannot be determined.
Note 3: During the initial power-up, VCC must exceed 2.25V for at least 0.5ms before OUT can go high.

Pin Configuration
PIN NAME FUNCTION
1 EN
Active-High Logic-Enable Input. Drive EN low to immediately de-assert the output to its false state
(OUT = low) independent of VIN. With VIN above VTH, drive EN high to assert the output to its true
state (OUT = high) after the adjustable delay period. Connect EN to VCC, if not used.
2 GND Ground
3 IN High-Impedance Monitor Input. Connect IN to an external resistive-divider to set the desired monitor
threshold. The output changes state when VIN rises above 0.5V and when VIN falls below 0.495V.
4 OUT
Active-High Sequencer/Monitor Output. Open-drain (MAX16052) or push-pull (MAX16053). OUT is
asserted to its true state (OUT = high) when VIN is above VTH and the enable input is in its true state
(EN = high) after the capacitor-adjusted delay period. OUT is de-asserted to its false state
(OUT = low) immediately after VIN drops below 0.495V or the enable input is in its false state
(EN = low). The MAX16052 open-drain output requires an external pullup resistor.
5 VCC
Supply Voltage Input. Connect a 2.25V to 28V supply to VCC to power the device. For noisy systems,
bypass with a 0.1μF ceramic capacitor to GND.
6 CDELAY
Capacitor-Adjustable Delay Input. Connect an external capacitor (CCDELAY) from CDELAY to GND
to set the IN-to-OUT and EN-to-OUT delay period. For VIN rising, tDELAY = (CCDELAY x 4.0 x 106) +
30μs. For EN rising, tPROP = (CCDELAY x 4.0 x 106) + 14μs.
Detailed Description
The MAX16052/MAX16053 family of high-voltage,
sequencing/supervisory circuits provide adjustable voltage
monitoring for inputs down to 0.5V. 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.
The MAX16052/MAX16053 perform voltage monitoring
using a high-impedance input (IN) with an internally fixed
0.5V threshold. When the voltage at IN falls below 0.5V
or when the enable input is de-asserted (EN = low) OUT
goes low. When VIN rises above 0.5V and the enable
input is asserted (EN = high), OUT goes high after a
capacitor-adjustable time delay.
With VIN above 0.5V, the enable input can be used to
turn on or off the output. Table 1 details the output state
depending on the various input and enable conditions.
Supply Input (VCC)
The device operates with a VCC supply voltage from 2.25V
to 28V. In order to maintain a 1.8% accurate threshold at
IN, VCC must be above 2.25V. When VCC falls below the
UVLO threshold, the output deasserts low. When VCC
falls below 1.2V, the output state is not guaranteed. For
noisy systems, connect a 0.1μF ceramic capacitor from
VCC to GND as close to the device as possible.

Monitor Input (IN)
Connect the center point of a resistive-divider to IN to
monitor external voltages (see R1 and R2 of Figure 4). IN
has a rising threshold of VTH = 0.5V and a falling threshold
of 0.495V (5mV hysteresis). When VIN rises above VTH
and EN is high, OUT goes high after the adjustable tDELAY
period. When VIN falls below 0.495V, OUT goes low after
a 18μs delay. IN has a maximum input current of 60nA, so
large value resistors are permitted without adding significant
error to the resistive-divider.
Adjustable Delay (CDELAY)
When VIN rises above VTH with EN high, 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). When the output asserts, CCDELAY is immediately
discharged. Adjust the delay (tDELAY) from when VIN
rises above VTH (with EN high) to OUT going high
according to the equation:
6
DELAY CDELAY
t C (4 10 ) (30µs)= × × Ω+
where tDELAY is in seconds and CCDELAY is in Farads.
Enable Input (EN)
The MAX16052/MAX16053 offer an active-high enable
input (EN). With VIN above VTH, drive EN high to force
OUT high after the capacitor-adjustable delay time. The
EN-to-OUT delay time (tPROP) can be calculated from
when EN goes above the EN threshold using the equation:
6
PROP CDELAY
t C (4 10 ) (14µs)= × × Ω+
where tPROP is in seconds and CCDELAY is in Farads.
Drive EN low to force OUT low within 300ns for the
MAX16052 and within 400ns for the MAX16053.
Output (OUT)
The MAX16052 offers an active-high, open-drain output
while the MAX16053 offers an active-high push-pull
output. The push-pull output is referenced to VCC. The
open-drain output requires a pullup resistor and can be
pulled up to 28V.
Applications Information
Input Threshold
The MAX16052/MAX16053 monitor the voltage on IN with
an external resistive-divider (Figure 4). R1 and R2 can
have very high values to minimize current consumption
due to low IN leakage currents (60nA max). Set R2 to
some conveniently high value (200kΩ for ±1% additional
variation in threshold, for example) and calculate R1
based on the desired monitored voltage using the following
formula:
MONITOR
TH
V
R1 R2 1
V

= × 

where VMONITOR is the desired monitored voltage and
VTH is the reset input threshold (0.5V).
Pullup Resistor Values (MAX16052 Only)
The exact value of the pullup resistor for the open-drain
output 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, 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.
Note that the ability to sink current is dependent on the
VCC supply voltage.
Ensuring a Valid OUT Down to VCC = 0V
(Push-Pull OUT)
In applications in which OUT must be valid down to VCC = 0V,
add a pulldown resistor between OUT and GND for the
push-pull output (MAX16053). The resistor sinks any
stray leakage currents, holding OUT low (Figure 3). The
value of the pulldown resistor is not critical; 100kΩ is large
enough not to load OUT and small enough to pull OUT to
ground. The external pulldown cannot be used with the
open-drain OUT output.

Typical Application Circuits
Figure 4 through Figure 6 show typical applications for the
MAX16052/MAX16053. Figure 4 shows the MAX16052
used with a pMOSFET in an overvoltage protection
circuit. Figure 5 shows the MAX16053 in a low-voltage
sequencing application using an nMOSFET. Figure 6
shows the MAX16053 used in a multiple output sequencing
application.
Using an n-Channel Device for Sequencing
In higher power applications, using an n-channel device
reduces the loss across the MOSFET as it offers a lower
drain-to-source on-resistance. However, an nMOSFET
requires a sufficient VGS voltage to fully enhance it for a
low RDS_ON. The application shown in Figure 5 shows
the MAX16053 in a switch sequencing application using
an nMOSFET.
Similarly, if a higher voltage is present in the system, the
open-drain version can be used in the same manner.
Power-Supply Bypassing
In noisy applications, bypass VCC to ground with a 0.1μF
capacitor as close to the device as possible. The additional
capacitor improves transient immunity. For fast-rising VCC
transients, additional capacitors may be required.
