LM5112MYX

LM5112MYX Description

The LM5112MYX from Texas Instruments is a low-side gate driver IC designed for high-performance power switching applications. Housed in an 8-pin MSOP package with surface-mount compatibility, it features a single-channel driver capable of delivering peak output currents of 3A (source) and 7A (sink). Operating within a 3.5V to 14V supply range, this driver ensures robust performance in demanding environments. With fast switching characteristics (14ns rise, 12ns fall times) and compatibility with logic thresholds (VIL = 0.8V, VIH = 2.3V), the LM5112MYX is optimized for efficiency and precision.
