LM5109ASD/NOPB TI Gate Driver | 8-WSON (4x4) | 1A Peak, 90ns Propagation Delay

Product Overview

The LM5109ASD/NOPB is a high-voltage gate driver from Texas Instruments, designed to drive both high-side and low-side N-channel MOSFETs in half-bridge or full-bridge configurations. It features a floating high-side driver capable of operating up to 100V, with a bootstrap supply voltage range of 8V to 14V. The device provides 1A peak gate drive current and fast propagation delays of typically 90ns, making it suitable for high-frequency switching applications. Housed in a compact 8-WSON (4x4) package, it offers excellent thermal performance and space savings.
