    INA286AIDR Typical application Circuitry


    The INA286AIDR is a precision current-shunt and power monitor with an²C- and SMBUS-compatible interface. It's designed to be versatile and is suitable for a range of applications, including power monitoring, overcurrent protection, and more. Here's how you can connect the INA286AIDR to a typical circuit:

    1. Current-Shunt Resistor Connection: For measuring the current, connect a shunt resistor across the pins IN+ (pin 5) and IN- (pin 4) of the INA286AIDR. This resistor's value is governed by the current range to be measured, and it should be carefully chosen for accurate current sensing.

    2. Power Supply Connection: The INA286AIDR operates from a 2.7V to 5.5V supply. Connect the V+ pin (pin 8) to your chosen supply voltage within this range, and ensure to decouple it with a suitable capacitor close to the pin to filter out any noise.

    3. Alert Functionality: If you wish to use the alert functionality of the INA286AIDR, connect the ALERT pin (pin 1) to a microcontroller or other alert handling circuitry. This pin can be used to signal over- or under-current conditions, or other programmable alerts.

    4. I²C/SMB US Interface: For digital communication with a microcontroller or processor, connect the SCL (pin 6) and SDA (pin 7) of the INA286AIDR to the corresponding I²C or SMB US lines of your controller. The right pull-up resistors must be used on these lines to ensure proper communication.

    5. Address Selection: The INA286AIDR provides an address pin (pin 2) for setting the²C address. Connect this pin according to the data sheet to select the correct address if multiple devices are on the same bus.

    6. Output Connection: The output voltage representing the sensed current is available at the OUT pin (pin 3). You can connect this to an ADC or other monitoring circuitry as needed. Ensure that this pin is within the tolerable input range of the connected device.

    7. Ground Connection: The GND pin (pin 5) of the INA286AIDR must be connected to the common ground of your system.

    8. Optional Filtering: If additional noise filtering is required, it may be advisable to add small filtering capacitors at the input and output of the INA286AIDR.

    9. Thermal Considerations: Proper thermal management and layout considerations should be made to ensure that the INA286AIDR operates within specified temperature limits.

    In summary, the INA286AIDR provides a sophisticated solution for current and power monitoring with minimal external components required. Careful connection of each pin and adherence to the recommended operating conditions as described in the data sheet will ensure reliable operation of the INA286AIDR in your specific application. Always refer to the most up-to-date data sheet and design guidelines provided by the manufacturer when implementing the INA286AIDR in your design.
