INA20x High-Side Measurement Current-Shunt Monitor
With Open-Drain Comparator and Reference
1 Features
3 Description
•
•
The INA200, INA201, and INA202 devices are highside current-shunt monitors with voltage output and
integrated comparator. The INA200–INA202 devices
can sense drops across shunts at common-mode
voltages from –16 V to 80 V. The INA200–INA202
devices are available with three output voltage
scales: 20 V/V, 50 V/V, and 100 V/V, with a
bandwidth up to 500-kHz.

0.6-V Internal Voltage Reference
Internal Open-Drain Comparator
Latching Capability on Comparator
Common-Mode Range: –16 V to 80 V
High Accuracy: 3.5% Maximum Error Over
Temperature
Bandwidth: 500 kHz (INA200)
Quiescent Current: 1800 μA (maximum)
Packages: SOIC-8, VSSOP-8
The INA200, INA201, and INA202 devices also
incorporate an open-drain comparator and internal
reference providing a 0.6-V threshold. External
dividers are used to set the current trip point. The
comparator includes a latching capability, which can
be made transparent by grounding (or leaving open)
the RESET pin.
The INA200, INA201, and INA202 devices operate
from a single 2.7-V to 18-V supply, drawing a
maximum of 1800 μA of supply current. Package
options include the very small VSSOP-8 and the
SOIC-8. All versions are specified over the extended
operating temperature range of –40°C to 125°C.

Hysteresis refers to the threshold (the threshold specification applies to a rising edge of a noninverting input) of a falling edge on the
noninverting input of the comparator; refer to Figure 1.
Specified by design.
VID refers to the differential voltage at the comparator inputs.
Open-drain output can be pulled to the range of 2.7 to 18 V, regardless of VS.
The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4 V.
The RESET input has an internal 2 MΩ (typical) pull-down. Leaving RESET open results in a LOW state, with transparent comparator
operation.

The INA200, INA201, and INA202 are designed to power-up with the comparator in a defined reset state as long as RESET is open or
grounded. The comparator is in reset as long as the power supply is below the voltage shown here. The comparator assumes a state
based on the comparator input above this supply voltage. If RESET is high at power-up, the comparator output comes up high and
requires a reset to assume a low state, if appropriate.

7 Detailed Description
7.1 Overview
The INA200, INA201, and INA202 devices are high-side current-shunt monitors with voltage output. The
INA200–INA202 devices can sense drops across shunts at common-mode voltages from –16 V to 80 V. The
INA200–INA202 devices are available with three output voltage scales: 20 V/V, 50 V/V, and 100 V/V, with up to
500-kHz bandwidth. The INA200, INA201, and INA202 devices also incorporate an open-drain comparator and
internal reference providing a 0.6-V threshold. External dividers are used to set the current trip point. The
comparator includes a latching capability, which can be made transparent by grounding (or leaving open) the
RESET pin. The INA200, INA201, and INA202 devices operate from a single 2.7 to 18-V supply, drawing a
maximum of 1800 μA of supply current. Package options include the very small MSOP-8 and the SO-8. All
versions are specified over the extended operating temperature range of –40°C to 125°C.

7.3.1 Basic Connections
Figure 26 shows the basic connections of the INA200, INA201, and INA202 devices. The input pins, VIN+ and
VIN–, should be connected as closely as possible with kelvin connections to the shunt resistor to minimize any
resistance in series with the shunt resistance.
Power-supply bypass capacitors are required for stability. Applications with noisy or high-impedance power
supplies may require additional decoupling capacitors to reject power-supply noise. Connect bypass capacitors
close to the device pins.

7.3.2 Selecting RS
The value chosen for the shunt resistor, RS, depends on the application and is a compromise between smallsignal accuracy and maximum permissible voltage loss in the measurement line. High values of RS provide better
accuracy at lower currents by minimizing the effects of offset, while low values of RS minimize voltage loss in the
supply line. For most applications, best performance is attained with an RS value that provides a full-scale shunt
voltage range of 50 mV to 100 mV. Maximum input voltage for accurate measurements is 500 mV, but output
voltage is limited by supply.
7.3.3 Comparator
The INA200, INA201, and INA202 devices incorporate an open-drain comparator. This comparator typically has
2 mV of offset and a 1.3-μs (typical) response time. The output of the comparator latches and is reset through
the RESET pin; see Figure 28.

7.4 Device Functional Modes
7.4.1 Input Filtering
An obvious and straightforward location for filtering is at the output of the INA200, INA201, and INA202 series;
however, this location negates the advantage of the low output impedance of the internal buffer. The only other
option for filtering is at the input pins of the INA200, INA201, and INA202 devices, which is complicated by the
internal 5 kΩ + 30% input impedance; this is illustrated in Figure 27. Using the lowest possible resistor values
minimizes both the initial shift in gain and effects of tolerance. The effect on initial gain is given by Equation 1:
Gain Error % = 100 - 100 ´
5kW
5kW + RFILT
(1)
Total effect on gain error can be calculated by replacing the 5-kΩ term with 5 kΩ – 30%, (or 3.5 kΩ) or 5 kΩ +
30% (or 6.5 kΩ). The tolerance extremes of RFILT can also be inserted into the equation. If a pair of 100 Ω 1%
resistors are used on the inputs, the initial gain error will be 1.96%. Worst-case tolerance conditions will always
occur at the lower excursion of the internal 5-kΩ resistor (3.5 kΩ), and the higher excursion of RFILT – 3% in this
case.
The specified accuracy of the INA200, INA201, and INA202 devices must then be combined in addition to these
tolerances. While this discussion treated accuracy worst-case conditions by combining the extremes of the
resistor values, it is appropriate to use geometric mean or root sum square calculations to total the effects of
accuracy variations.
7.4.2 Accuracy Variations as a Result of VSENSE and Common-Mode Voltage
The accuracy of the INA200, INA201, and INA202 current shunt monitors is a function of two main variables:
VSENSE (VIN+ – VIN–) and common-mode voltage, VCM, relative to the supply voltage, VS. VCM is expressed as
(VIN+ + VIN–)/2; however, in practice, VCM is seen as the voltage at VIN+ because the voltage drop across VSENSE
is usually small.
This section addresses the accuracy of these specific operating regions:
• Normal Case 1: VSENSE ≥ 20 mV, VCM ≥ VS
• Normal Case 2: VSENSE ≥ 20 mV, VCM < VS
• Low VSENSE Case 1: VSENSE < 20 mV, –16 V ≤ VCM < 0
• Low VSENSE Case 2: VSENSE < 20 mV, 0 V ≤ VCM ≤ VS
• Low VSENSE Case 3: VSENSE < 20 mV, VS < VCM ≤ 80 V
7.4.2.1 Normal Case 1: VSENSE ≥ 20 mv, VCM ≥ VS
This region of operation provides the highest accuracy. Here, the input offset voltage is characterized and
measured using a two-step method. First, the gain is determined by Equation 2.
VOUT1 - VOUT2
G=
100mV - 20mV
where
•
•
VOUT1 = Output Voltage with VSENSE = 100 mV
VOUT2 = Output Voltage with VSENSE = 20 mV
(2)
Then the offset voltage is measured at VSENSE = 100 mV and referred to the input (RTI) of the current shunt
monitor, as shown in Electrical Characteristics: Current-Shunt Monitor.
VOUT1
VOSRTI (Referred-To-Input) =
- 100mV
G
(3)
In the Typical Characteristics, Figure 7 curve shows the highest accuracy for the this region of operation. In this
plot, VS = 12 V; for VCM ≥ 12 V, the output error is at its minimum. This case is also used to create the VSENSE ≥
20-mV output specifications in Electrical Characteristics: Current-Shunt Monitor .

Device Functional Modes (continued)
7.4.2.2 Normal Case 2: VSENSE ≥ 20 mv, VCM < VS
This region of operation has slightly less accuracy than Normal Case 1 as a result of the common-mode
operating area in which the part functions, as seen in the Figure 7 curve (Figure 7). As noted, for this graph VS =
12 V; for VCM < 12 V, the Output Error increases as VCM becomes less than 12 V, with a typical maximum error
of 0.005% at the most negative VCM = –16 V.
7.4.2.3 Low VSENSE Case 1: VSENSE < 20 mV, –16 V ≤ VCM < 0;
and Low VSENSE Case 3: VSENSE < 20 mV, VS < VCM ≤ 80 V
Although the INA200 family of devices are not designed for accurate operation in either of these regions, some
applications are exposed to these conditions. For example, when monitoring power supplies that are switched on
and off while VS is still applied to the INA200, INA201, or INA202 devices, it is important to know what the
behavior of the devices will be in these regions.
As VSENSE approaches 0 mV, in these VCM regions, the device output accuracy degrades. A larger-than-normal
offset can appear at the current shunt monitor output with a typical maximum value of VOUT = 300 mV for
VSENSE = 0 mV. As VSENSE approaches 20 mV, VOUT returns to the expected output value with accuracy as
specified in the Electrical Characteristics: Current-Shunt Monitor. Figure 31 illustrates this effect using the
INA202 (Gain = 100).

7.4.2.4 Low VSENSE Case 2: VSENSE < 20 mV, 0 V ≤ VCM ≤ VS
This region of operation is the least accurate for the INA200 family. To achieve the wide input common-mode
voltage range, these devices use two op amp front ends in parallel. One op amp front end operates in the
positive input common-mode voltage range, and the other in the negative input region. For this case, neither of
these two internal amplifiers dominates and overall loop gain is very low. Within this region, VOUT approaches
voltages close to linear operation levels for Normal Case 2. This deviation from linear operation becomes
greatest the closer VSENSE approaches 0 V. Within this region, as VSENSE approaches 20 mV, device operation is
closer to that described by Normal Case 2. Figure 32 illustrates this behavior for the INA202. The VOUT maximum
peak for this case is tested by maintaining a constant VS, setting VSENSE = 0 mV and sweeping VCM from 0 V to
VS. The exact VCM at which VOUT peaks during this test varies from part to part, but the VOUT maximum peak is
tested to be less than the specified VOUT tested limit.

7.4.3 Transient Protection
The –16 to 80-V common-mode range of the INA200, INA201, and INA202 devices is ideal for withstanding
automotive fault conditions ranging from 12-V battery reversal up to 80-V transients, since no additional
protective components are needed up to those levels. In the event that the INA200, INA201, and INA202 devices
are exposed to transients on the inputs in excess of their ratings, then external transient absorption with
semiconductor transient absorbers (such as Zeners) will be necessary. Use of MOVs or VDRs is not
recommended except when they are used in addition to a semiconductor transient absorber. Select the transient
absorber such that it will never allow the INA200, INA201, and INA202 devices to be exposed to transients
greater than 80 V (that is, allow for transient absorber tolerance, as well as additional voltage due to transient
absorber dynamic impedance). Despite the use of internal Zener-type ESD protection, the INA200, INA201, and
INA202 devices do not lend themselves to using external resistors in series with the inputs since the internal gain
resistors can vary up to ±30%. (If gain accuracy is not important, then resistors can be added in series with the
INA200, INA201, and INA202 inputs with two equal resistors on each input.)
7.4.4 Output Voltage Range
The output of the INA200, INA201, and INA202 devices is accurate within the output voltage swing range set by
the power supply pin, Vs. This performance is best illustrated when using the INA202 (a gain of 100 version),
where a 100-mV full-scale input from the shunt resistor requires an output voltage swing of 10 V, and a powersupply voltage sufficient to achieve 10 V on the output.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The INA20x series is designed to enable easy configuration for detecting overcurrent conditions and current
monitoring in an application. This device is individually targeted towards overcurrent detection of a single
threshold. However, this device can also be paired with additional devices and circuitry to create more complex
monitoring functional blocks.

8.2.1 Design Requirements
The device measures current through a resistive shunt with current flowing in one direction, thus enabling
detection of an overcurrent event only when the differential input voltage exceeds the threshold limit. When the
current reaches the set limit of the divider R1/R2, the output of CMPOUT will transition high which will turn Q1 on
and pull the gate of the Pass-FET low and turn off the flow off current.

8.2.2 Detailed Design Procedure
Figure 33 shows the basic connections of the device. The input terminals, IN+ and IN –, should be connected as
closely as possible to the current-sensing resistor to minimize any resistance in series with the shunt resistance.
Additional resistance between the current-sensing resistor and input terminals can result in errors in the
measurement. When input current flows through this external input resistance, the voltage developed across the
shunt resistor can differ from the voltage reaching the input terminals.
Use the Gain of the INA20x and shunt value to calculate the OUT voltage for the desired trip current. Configure
R1 and R2 so that the current trip point is equal the 0.6-V reference voltage.

9 Power Supply Recommendations
The input circuitry of the INA200, INA201, and INA202 devices can accurately measure beyond the power-supply
voltage, Vs. For example, the Vs power supply can be 5 V, whereas the load power-supply voltage is up to 80 V.
The output voltage range of the OUT pin, however, is limited by the voltages on the power-supply pin.

10 Layout
10.1 Layout Guidelines
•
•
Connect the input pins to the sensing resistor using a Kelvin or 4-wire connection. This connection technique
ensures that only the current-sensing resistor impedance is detected between the input pins. Poor routing of
the current-sensing resistor commonly results in additional resistance present between the input pins. Given
the very low ohmic value of the current resistor, any additional high-current carrying impedance can cause
significant measurement errors.
The power-supply bypass capacitor must be placed as close as possible to the supply and ground pins. The
recommended value of this bypass capacitor is 0.1 μF. Additional decoupling capacitance can be added to
compensate for noisy or high-impedance power supplies.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
