Current Regulation/Management Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance when sourcing. Confirm package type matches SOT-23-5 requirements. Check datasheet for humidity sensitivity level details before assembly. Ensure ordering quantity aligns with reel or cut tape availability from authorized distributors.

Current Regulation/Management Selection Notes

Select this component for applications requiring high-side current monitoring with low static power consumption. The wide input voltage range suits systems operating between 2.7 V and 60 V. Consider the SOT-23-5 package for space-constrained PCB layouts. Verify thermal performance within the specified operating temperature range.

Current Regulation/Management Part Context

This part belongs to the INA168 series of current monitors. It shares functional similarities with the INA138 but offers an extended input voltage range up to 60 V compared to the INA138's 36 V limit. Both devices utilize the same SOT-23-5 package and offer comparable accuracy specifications for general-purpose monitoring tasks.

Current Regulation/Management Replacement Considerations

INA138NA/250 is a similar alternative with a lower maximum input voltage of 36 V. Verify that the system voltage does not exceed the substitute's rating. Both parts share the same package and accuracy, ensuring pin compatibility.
