LM5100AM/NOPB

LM5100AM/NOPB Description

The LM5100AM/NOPB from Texas Instruments is a high-performance half-bridge gate driver IC designed for robust power MOSFET and IGBT control. Operating within a 9V to 14V supply range, it features independent high- and low-side drivers, enabling precise switching in high-voltage applications. With a maximum bootstrap voltage of 118V, it supports high-side driving in demanding power topologies. The device delivers 3A peak output current (source/sink), ensuring fast switching with 430ns rise and 260ns fall times (typical), minimizing switching losses. Packaged in an 8-pin SOIC, it is RoHS3 compliant and suitable for surface-mount applications.
