Procurement Notes

Verify the specific suffix XTSA1 against official Infineon documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the target PCB footprint for the PG-SOT23-6 package. Cross-reference the revision level (e.g., Rev. 2.2) with the latest datasheet to validate pinout and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a single-channel driver with differential signaling is required for high-side applications. The 8 A output current suits medium-power MOSFET switching needs. Consider the 45 ns propagation delay and 6.5/4.5 ns transition times for switching frequency requirements. Verify that the 4.5–20 V supply range aligns with the system's bootstrap or isolated power design constraints.
