Procurement Notes

Verify the specific suffix '+T' indicates tape and reel packaging when ordering. Confirm that the 20-TQFN footprint matches your PCB design requirements. Ensure the 58V maximum rating aligns with your system's peak voltage conditions. Check RoHS compliance status if required by your manufacturing standards. Validate thermal performance given the exposed pad package type.

Selection Notes

Choose this component when integrated power limiting and current foldback are required alongside voltage protection. Consider the 20-TQFN package size constraints during layout planning. Evaluate the 1.4mA supply current against low-power system budgets. Verify that the 5.5V minimum operating voltage suits your lowest expected supply level. Assess thermal dissipation needs for the exposed pad configuration.
