Procurement Notes

Verify the specific suffix 'SD' corresponds to the WSON-10 package variant when ordering. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance as per Texas Instruments standards. Ensure the selected part number matches the required pinout and thermal characteristics for the intended PCB layout. Cross-reference the datasheet revision to confirm compatibility with existing design specifications.

Selection Notes

Select this component for applications requiring a dedicated half-bridge driver with high peak current capability. The 5 A output drive strength is suitable for driving medium-power MOSFETs or IGBTs. Consider the 4.5 V to 5.5 V supply range when designing the bootstrap or isolated supply circuit. The wide operating temperature range makes it suitable for industrial environments where thermal stability is critical.

Part Context

The LM5113 belongs to the LM511x series of gate drivers from Texas Instruments, which are optimized for high-voltage power conversion. This series typically includes variants for half-bridge and low-side configurations. The LM5113 specifically targets half-bridge topologies, offering integrated features such as shoot-through prevention and fast switching speeds to enhance efficiency in power electronics designs.
