FAQs

What is INA169NA/250?

The INA169NA/250 is a high-side current shunt monitor designed by Texas Instruments. It is specifically tailored for precision current sensing in applications like motor control, power management, and battery charging systems.

How Does INA169NA/250 Work?

The INA169NA/250 operates by sensing the voltage drop across a current shunt resistor to measure the current flowing through a circuit. It provides an accurate representation of the load current by amplifying the small voltage developed across the shunt resistor. This amplified voltage output is proportional to the load current being monitored.

How Many Pins does INA169NA/250 have and What are the Functions of the Pinout Configuration?

The INA169NA/250 is housed in a 5-pin SOT-23 package. The pinout configuration includes:

  • V+: Positive power supply pin.
  • V-: Negative power supply pin.
  • VS: Voltage sense input pin.
  • OUT: Voltage output pin.
  • GND: Ground pin.

What are the Pros and Cons of INA169NA/250?

Pros:

  • Precision Current Sensing: Provides accurate monitoring of load currents.
  • High-Side Sensing: Suitable for applications requiring high-side current monitoring.
  • Small Form Factor: The SOT-23 package is space-efficient and suitable for compact designs.
  • Wide Supply Voltage Range: Supports a broad range of supply voltages for versatility.
  • Low Power Consumption: Operates with low power, ideal for battery-powered applications.

Cons:

  • Temperature Drift: May exhibit drift with temperature variations, requiring compensation in some applications.
  • External Components: Additional filtering or amplification may be needed for specific system requirements.
  • Accuracy vs. Cost: Higher accuracy versions may come at a higher cost compared to lower precision current monitors.

Are There Any Equivalents/Alternatives to INA169NA/250 for Recommendation?

  • The INA240A1 from Texas Instruments is a comparable high-side current shunt monitor.
  • Alternatives to the INA169NA/250 include the MAX4080 from Maxim Integrated and the LT6108 from Analog Devices.
