INA381EVM
1 Overview
The INA381 family of current-shunt monitors (also called current-sense amplifiers) can sense voltage
drops across shunts at common-mode voltages from –0.3 V to +26 V, independent of the supply voltage.
Four fixed gains are available: 20 V/V, 50 V/V, 100 V/V, and 200 V/V. These devices operate from a
single 2.7-V to 5.5-V power supply, drawing a maximum of 1000 μA of supply current per amplifier
channel. A comparator is included to provide an active low alert signal when the output exceeds a user
defined voltage. The alert function operates in either continuous mode or latch mode to respectively
indicate whether a certain overvoltage or overcurrent event is occurring or has occurred. The INA381
devices are currently available in a 8-pin WSON surface-mount package with a thermal pad as the device
ground connection. Table 1 lists the available gain options.

INA381EVM
2 Hardware
The INA381 is an op amp current-sense solution that provides ease of use and high performance. The
INA381EVM is intended to provide basic functional evaluation of this device family. The fixture layout is
not intended to be a model for the target circuit, nor is it laid out for electromagnetic compatibility
(EMC) testing. The INA381EVM consists of one PCB with an option to snap apart into four individual
PCBs; one for each of the four devices (INA381A1, INA381A2, INA381A3, and INA381A4).
2.1 Features
The layout of the INA381EVM printed-circuit board (PCB) is designed to provide the following features:
• Evaluation of all gain options for the INA381Ax
• Ease of access to device pins with test points
• Capability to evaluate high-side and low-side configurations
• Ability to set the comparator trip voltage.
See the INA381 data sheet for comprehensive information about the INA381 family of devices.
3 Quick Start Setup and Use
The following are instructions to set up and use the INA381 devices of the INA381EVM. For the following
instructions, x = A to D.
Step 1. Connect ground reference of that supply to the GND test point TPx1 or TPxV1 and connect
an external dc supply voltage between 2.7 V and 5.5 V to the Vs test point TPx2 or TPxV2.
Step 2. Connect the input per Section 3.1.
3.1 Measurements
The INA381EVM enables the user to either simulate the voltage developed across a sense resistor based
on a given set of system conditions or to connect remotely to an existing shunt already included in an
example application.
The following procedures are used to configure a measurement evaluation without a shunt. For the
following instructions, x = A to D.
Step 1. Stack a floating differential voltage supply on top of a common mode voltage by connecting
the ground of the floating differential voltage supply to the positive voltage output of the
common mode voltage supply. Adjust common mode voltage to any value between –0.2 V
and +26 V; the data sheet condition is 12 V.
Step 2. Connect the positive polarity of the differential voltage to IN+ (TPx3 or TPxV3) and the
negative polarity to IN– (TPx5 or TPxV5) test points. (IN+ pin must be the more positive of
the two inputs.)
Step 3. Measure the output voltage at the VOUT test point (TPx4 or TPxV4).
NOTE: The output voltage is equal to the gain of the device multiplied by the differential voltage
measured directly at the device input pins.
3.2 Alert Function
The INA381EVM provides an alert pin that will pull low when the output exceeds a user-defined voltage.
With the alert function, there are two different modes: latch mode and continuous mode. The device enters
latch mode when RESET (pin 4) is pulled to VS+ (pin 2). When reset is pulled to GND (bottom pad) the
device enters continuous mode and resets the device if it is latched and the output voltage is below
CMPREF (pin 5). CMPREF determines at what voltage the ALERT pin goes low. This value is
conveniently adjustable to any voltage between GND and VS+ with the onboard potentiometer. When the
voltage on VOUT exceeds the voltage of CMPREF, the onboard LED turns on.

INA381EVM
4 Circuitry
This section summarizes the INA381EVM components. For the following instructions, x = A to D.
4.1 Cx1, Cx2
Cx1 and Cx2 are 10-μF and 0.1-μF supply bypass capacitors respectively.
4.2 Cx3, Rx2, Rx4
Cx3, Rx2, and Rx4 footprints are for customizing the input pi-filter to the INA381 device. Default values
are 0 Ωand 1000 pF. However, no capacitor is installed.
4.3 Cx4, Rx3
Cx4 and Rx3 are footprints for a customizable output filter. Default values are 0 Ωand 1000 pF. However,
no capacitor is installed.
4.4 Ux1
Ux1 is the test-device location. Four device boards are supplied with the INA381EVM. Each board is
populated with one of the available device gains: 20 V/V, 50 V/V, 100 V/V, or 200 V/V. This option enables
users to test the devices and determine the gain setting best suited for a given application. The following
list of factors is involved in selecting the appropriate device:
• Select INA381 for unidirectional applications only.
• The differential input voltage is applied across the inputs, or developed based on the load current that
flows through the shunt resistor connected across the inputs.
• The most limiting factor that requires attention to be given to device selection is the output voltage.
• The selected device must allow the output voltage to remain within the acceptable range after the
Vsense voltage (IN+ – IN–) is amplified by the respective device gain. The max output voltage must
remain within the range of 10 mV above ground to 100 mV below the supply voltage.
• Choose an appropriate gain and sense resistor to create the largest appropriate output swing possible
and to minimize error.
4.5 Rx5, Cx5
Rx5 is a 50-kΩtrimming potentiometer that allows the user to set the CMPREF voltage without having to
use an additional power supply. Cx5 is a bypass capacitor that is meant to absorb any transients that
would otherwise feed into the CMPREF pin.
4.6 Rx1, Rx7, Qx1, Dx1
Rx1 serves as a pull-up resistor that keeps the ALERT pin voltage around VS+ when the ALERT pin is
open drain (inactive) and as an impedance path that prevents VS+ from shorting to GND when the ALERT
pin goes low (active). Qx1 serves as a switch controlled by the ALERT pin. When Qx1 switches on
(ALERT goes active low), Dx1 turns on, which notifies the user that voltage at VOUT exceeded the
voltage at CMPREF. Rx7 limits the current through Dx1.
4.7 Jx
Jx controls whether the device uses continuous mode or latch mode. RST shorted to VS+ puts the device
in latch mode. RST shorted to GND puts the device in continuous mode.
4.8 Voltages Inputs
The IN+ (TPx3 or TPxV3) and IN– (TPx5 or TPxV5) inputs accept a differential voltage that is amplified by
the selected device gain and is presented at the VOUT test point (TPx04 or TPx14). These inputs can
also be used to connect the differential voltage developed across an external shunt in an existing circuit.
The acceptable differential input voltage range and polarity are determined by the supply voltage and gain
of the selected device.
