For dual-sourcing or a second-source option, the LM5106MM/NOPB is a half-bridge driver with 1.2 A peak current and a different drive architecture — it is not a pin-compatible drop-in, but it fills a similar role if the design can accommodate the half-bridge topology and lower drive strength.","metaTitle":"UCC27321DR Low-Side Gate Driver, 9A Peak, 8-SOIC","metaDescription":"UCC27321DR low-side gate driver from Texas Instruments: 9A peak source/sink, 20ns rise/fall, 4V–15V supply, -40°C to 105°C, 8-SOIC.
