The 8-SOIC package (3.90 mm body width) is a common footprint that fits compact PCB layouts and is compatible with standard reflow soldering profiles. The tube shipping medium is typical for prototype and low-to-medium volume builds; for higher volumes, the part is also available in tape-and-reel under a different order code variant. ## Sourcing and lifecycle — active, ROHS3, quoted to order The LM5109BMA/NOPB carries an active product status from Texas Instruments, with ROHS3 compliance (the NOPB suffix indicates lead-free / RoHS-compliant). The active lifecycle means no last-time-buy risk for the foreseeable future, and the ROHS3 compliance satisfies the majority of global regulatory requirements for electronic equipment placed on the EU and other markets.","metaTitle":"LM5109BMA/NOPB Gate Driver, Half-Bridge, 1A, 8-SOIC","metaDescription":"TI LM5109BMA/NOPB half-bridge gate driver for N-channel MOSFETs. 1A peak drive, 108V bootstrap, 15ns rise/fall, -40 to 125°C.
