    Selection Notes

    • Check the reference design before finalising external components.
    • Thermal pad layout drives continuous current capability.
    • Confirm the suffix — package and grade change between variants.
    • Datasheet limits apply at the stated test conditions; derate for your ambient.
    • Protection thresholds are set by external resistors in most designs.
