DATASHEET

Multiple Voltage Supervisory ICs
ISL6131, ISL6132
Features
The ISL6131 and ISL6132 are a family of high-accuracy,
multi-voltage supervisory ICs designed to monitor voltages
greater than 0.7V in applications ranging from
microprocessors to industrial power systems. The ISL6131 is
an undervoltage four-supply supervisor, and the ISL6132 is a
two-voltage supervisor monitoring for undervoltage (UV) and
overvoltage (OV) conditions.
• Operates from 1.5V to 5.5V Supply Voltage
Both ICs feature four external resistor programmable voltage
monitoring (VMON) inputs, each with a related STATUS output
that individually reports the related monitor input condition. In
addition, there is a Power-Good (PGOOD) signal that asserts
high when the STATUS outputs are in their correct state. A
stability delay of approximately 160ms ensures that the
monitored supply is stable before STATUS and PGOOD are
released to go high. The PGOOD and STATUS outputs are
open-drain to allow OR’ing of the signals and interfacing to a
wide range of logic levels.
• VDD Lock-Out
STATUS and PGOOD outputs are guaranteed to be valid with IC
bias lower than 1V, eliminating concern about STATUS and
PGOOD outputs during IC bias up and down. VMON inputs are
designed to ignore momentary transients on the monitored
supplies.

PGOOD
On the ISL6131, PGOOD is the Boolean AND function of all four STATUS outputs.
On the ISL6132, PGOOD is for the AB pair and signals high when the monitored voltage is within the specified window
and the A and B STATUS output states are correct.
This is an open-drain output and is to be pulled high to the appropriate level with an external resistor to a VDD
maximum level.
NA

PGOOD2
PGOOD2 is for the CD pair and signals high when the monitored voltage is within the specified window and when the
C and D STATUS output states are correct.
This is an open-drain output and is to be pulled high to the appropriate level with an external resistor to a VDD
maximum level.
On the ISL6131, these inputs provide a programmable UV threshold referenced to an internal 0.633V. The related
STATUS output asserts when the related input > internal reference voltage.
On the ISL6132, these inputs provide a programmable UV and OV threshold referenced to an internal 0.633V
reference. In the ‘AB’ pair, VMON_A is the UV input, and VMON_B is the OV input. In the ‘CD’ pair, VMON_C is the UV
input, and VMON_D is the OV input.
These inputs have a 30µs glitch filter to prevent PGOOD reset caused by a transient.

FUNCTION DESCRIPTION
On the ISL6131, each STATUS provides a high signal through pull-up resistors about 160ms after its related VMON
has continuously been > Vuv_vth. This delay is for stabilization of monitored voltages. STATUS de-asserts and pulls
low upon VMON not being satisfied for about 30µs.
On the ISL6132, the STATUS outputs indicate compliance with a high output state for each pair of monitors.

Description and Operation
The ISL6131 is a four-voltage, high-accuracy, supervisory IC
designed to monitor multiple voltages greater than 0.7V relative
to Pin 10 of the IC.
Upon VDD bias power-up, the STATUS and PGOOD outputs are
held correctly low once VDD is as low as 1V. Once biased to 1.5V,
the IC continuously monitors from one to four voltages
independently through external resistor dividers, comparing each
voltage monitoring (VMON) pin voltage to an internal 0.633V
(VVMONvth) reference.
With the EN input driven high or open, as each VMON input rises
above VVMONvth, a timer is set to ensure ~160ms of continuous
compliance. Then the related STATUS output is released to be
pulled high. The STATUS outputs are open-drain to allow OR’ing of
these signals and interfacing to a logic high level up to VDD. The
STATUS outputs are designed to reject short transients (~30μs)
on the VMON inputs. Once all STATUS outputs are high, a
Power-Good (PGOOD) output signal is generated high to indicate
that all monitored voltages are greater than minimum
compliance level.
Once any VMON input falls below VVMONvth for longer than the
glitch filter time, both the PGOOD and the related STATUS output
are pulled low. The other STATUS outputs remain high as long as
their corresponding VMON voltage remains valid and the PGOOD
validation process is reset.
Figure 1 shows the ISL6131 typical application schematic, and
Figure 3 is an operational timing diagram. See Figures 10 to 17 for
ISL6131 function and performance. Figures 10 and 11 show the
VDD rising along with STATUS and PGOOD response. Figures 12
and 13 illustrate VMON falling below VVMONvth, and Figure 14
shows VMON rising above VVMONvth with STATUS and PGOOD
response. Figure 15 shows VDD failing, with STATUS and PGOOD
response. Figures 16 and 17 show ENABLE to STATUS and PGOOD
timing.
If less than four voltages are being monitored, connect the
unused VMON pins to VDD for proper operation. All unused
STATUS outputs can be left open.
The ISL6132 is a dual voltage monitor for undervoltage and
overvoltage compliance. Figure 2 shows the typical ISL6132
implementation schematic, and Figure 4 is the operational timing
diagram.
There are two pairs of monitors, each with an undervoltage
(UVMON) input and an overvoltage (OVMON) input, along with
associated STATUS and PGOOD outputs.
Upon VDD bias power-up, the STATUS and PGOOD outputs are
held correctly low, once VDD is as low as 1V. Once biased to 1.5V,
the IC continuously monitors the voltage through external resistor
dividers, comparing each VMON pin voltage to an internal 0.633V
reference. At proper bias, OVSTATUS is pulled high, and
UVSTATUS and PGOOD are pulled low. Once the UVMON
5
input > VMON Vth continuously for ~160ms, its associated
STATUS output releases high, indicating that the minimum
voltage condition has been met. As both UVMON and OVMON
inputs are satisfied, the PGOOD output is released to go high,
indicating that the monitored voltage is within the specified
window. Figure 18 shows this performance for a 4V to 5V
window.
When VMON does not satisfy its voltage high or low criteria for
more than the glitch filter time, the associated STATUS and
PGOOD are pulled low. Figures 19 and 20 show this performance
for a 4V to 5V compliant window.
Figures 21 through 23 show the VMON glitch filter timing to
STATUS and PGOOD notification and transient immunity.
The ENABLE input, when pulled low, allows the monitoring and
reporting functions to be disabled. Figure 24 shows ENABLE high
to PGOOD timing for compliant voltage.
When choosing resistors for the divider, remember to keep the
current through the string bounded by power loss tolerance at the
top end and noise immunity at the bottom end. For most
applications, total divider resistance in the 10kΩ -100kΩ range
is advisable, with 1% tolerance resistors being used to reduce
monitoring error.
Figures 1 and 2 show that choosing the two resistor values is
straightforward for the ISL6131, because the ratio of resistance
should equal the ratio of the desired trip voltage to the internal
reference, 0.633V.
For the ISL6132, two dividers of two resistors each can be
employed to monitor the OV and UV levels for each voltage.
Otherwise, use a single three-resistor string for each voltage. In
the three-resistor divider string, the ratio of the desired
overvoltage trip point to the internal reference is equal to the
ratio of the two upper resistors to the lowest (GND connected)
resistor. The desired undervoltage trip point ratio to the internal
reference voltage is equal to the ratio of the uppermost (voltage
connected) resistor to the two lower resistors, as shown in the
following example:
1. Establish lower and upper trip level: 3.3V ±20% or 2.64V (UV)
and 3.96V (OV)
2. Establish total resistor string value: 10kΩ, Ir = divider current
3. (Rm + Rl) * Ir = 0.623V @ UV and Rl * Ir = 0.633V @ OV
4. Rm + Rl = 0.623V/Ir @ UV => Rm + Rl =
0.623V/(2.64V/10kΩ) = 2.359kΩ
5. Rl = 0.633V/Ir @ OV => Rl = 0.633V/(3.96V/10kΩ) = 1.598kΩ
6. Rm = 2.359kΩ - 1.598kΩ = 0.761kΩ
7. Ru = 10kΩ - 2.397kΩ = 7.641kΩ
Choose standard value resistors that most closely approximate
these ideal values. Choosing a different total divider resistance
value may yield a more ideal ratio with available resistors values.

either an undervoltage or an overvoltage condition on 5V and
12V supplies to a ±10% tolerance. There is an OV and a UV
STATUS output for each of the two supplies and individual
AND’ed PGOOD outputs when each voltage is within the
programmed voltage range. An OFF LED indicates compliance to
the voltage range upper and lower limits.
The ENABLE inputs enable or disable the voltage monitoring
functions for each monitor supply.

Using the ISL6131, ISL6132 for Negative
Voltage Monitoring Applications
Using the ISL6131 for System Voltage and
Over-Temperature Monitoring
The ISL6131, ISL6132 can be used for -V monitoring because it
monitors any voltage that is more positive relative to its GND pin.
With correct bias differential, these parts can monitor any
voltage, regardless of polarity or amplitude.
As a multi-voltage monitoring IC, the ISL6131 can monitor
over-temperature as well as voltage for more complete coverage
of system stability. Using a Negative Temperature Coefficient
(NTC) passive device in place of one of the resistors in a VMON
divider provides over-temperature monitoring either locally or
remotely.
Using the ISL6131 for “Lossless” Sequencing
Applications
The ISL6131 can be used in a “lossless” sequencing application
in which a monitored output voltage determines the start of the
next sequenced turn-on. As shown in Figure 7, VMON_A input
looks at the common VIN of several DC-DC converters and
enables DC-DC_A with STATUS _A, once both VIN and ENABLE are
satisfied. VMON_B monitors the output of DC-DC_A, and when
the acceptable output voltage is reached, DC-DC_B is enabled
with STATUS_B output. This sequencing pattern continues until
all DC-DC outputs are on, at which time PGOOD signal is
released. A delay of 160ms from VMON > VVMONVth to STATUS
high ensures stability at each step prior to subsequent turn-on.
Additional ISL6131s can be employed in parallel to sequence any
number of DC-DC convertors in this fashion.
Evaluations of this application configuration have involved the
QT0805T-202J, QT0805Y-502J and QT0805Y-103J NTCs from
Quality Thermistor.
ISL6131 over-temperature monitoring is not as accurate as
specific temperature monitor ICs, but this implementation
provides a cost-efficient solution with 5% tolerances achievable.
See Figures 8 and 9 for over-temperature sensing configuration
and operation results. In this example, the desired maximum
temperature is 100°C. The QT0805Y-103J NTC was placed at the
end of 3 feet of twisted pair wire to emulate a remote sensing
application. According to the Quality Thermistor data sheet, this
NTC device has a +25°C value of 10K and a +100°C value of
0.923K. An accompanying standard value resistor of 3.83K was
chosen for the divider so that at 100°C, VMON ~0.633V with the
bias voltage at 3.3V.
The resulting falling VMON trip point with the configuration
shown is ~0.634V, with ~0.642V for rising, which equates to
~95°C for under-temperature and ~97°C for over-temperature,
respectively. Choosing the standard resistor value above and
below R1 allows for small adjustments in the temperature trip
point.
