This datasheet introduces the features of TC4420/TC4429 MOSFET drivers, including their characteristics and application scenarios.
The TC4420 (non‑inverting) and TC4429 (inverting) are 6 A peak, high‑speed MOSFET driver ICs designed for switch‑mode power supplies, motor control, and Class D audio. They feature latch‑up protection, ESD protection, and CMOS/TTL compatible inputs.
The document lists detailed electrical characteristics, typical performance curves, and pin‑function tables, including supply voltage range, rise/fall times, propagation delay, and output current capabilities. Pin descriptions and layout notes for SOIC, DFN, and TO‑220 packages are also provided.
