LM2105DR TI Gate Driver | 8-SOIC | 3A Sink/Source, 100V

Product Overview

The LM2105DR from Texas Instruments is a high-voltage, high-speed gate driver designed for driving N-channel MOSFETs and IGBTs in half-bridge and full-bridge configurations. With a 100V bootstrap voltage rating and 3A peak sink/source current capability, it provides robust drive strength for power conversion applications. The device features independent high-side and low-side inputs with matching propagation delays, ensuring efficient switching performance. Housed in an 8-pin SOIC package, the LM2105DR is optimized for space-constrained designs requiring high power density.
