INA381: Pin compatible alternative for the INA381

Roy van der Hulst

Part Number: INA381
Other Parts Discussed in Thread: INA300

Hi,

We use the INA381A4IDGSR (VSSOP-10) in our design for overcurrent protection. We want to update the design and lower the power consumption. Is there a pin compatible alternative available with a lower Quiescent current?

Thank you very much!

Hello Roy,

There are no pin for pin alternatives available for the INA381, but we do have other parts available with lower quiescent current. The INA300 has a significant drop in Iq but only features an alert comparator output. Without the comparator, you can sort through our catalog of current-sensing devices by going to our catalog and sorting by the quiescent current levels: https://www.ti.com/amplifier-circuit/current-sense/products.html#sort=236max;asc&

Let me know if you have any more questions,

Levi DeVries
