LM5104 High Voltage Half-Bridge Gate Driver with Adaptive Delay
The LM5104 is a high‑voltage, dual‑output gate driver designed for driving the high‑side and low‑side N‑channel MOSFETs in synchronous buck or half‑bridge configurations. It features adaptive delay to prevent shoot‑through, a programmable dead‑time resistor, and an integrated bootstrap diode. The device operates from a single PWM input and supports supply voltages up to 118 V DC.
The document provides detailed pin descriptions, absolute maximum ratings, electrical characteristics, typical performance graphs, and mechanical data for the SOIC‑8 and LLP‑10 packages. It also includes recommended land‑pattern dimensions, packaging drawings, and compliance statements for life‑support and banned‑substance policies.
