Procurement Notes

Verify the specific suffix 'ADR' corresponds to the SOIC-8 package and reel packaging configuration as listed in official Texas Instruments documentation. Confirm that the ordering part number matches the exact pinout and thermal requirements of the target PCB layout. Ensure compliance with RoHS directives and check for any recent product change notifications regarding assembly sites or material composition updates before finalizing procurement orders.

Selection Notes

Select this component when a compact solution is required for driving N-channel MOSFETs in half-bridge configurations. The 3 A peak current rating is sufficient for moderate gate charge loads, while the 120 V boot capability accommodates standard industrial bus voltages. Consider the SOIC-8 footprint constraints and verify that the 8 V minimum supply voltage aligns with the system's available logic levels and operating conditions.
