This file is about TC4426A/TC4427A/TC4428A's datasheet, which introduces the features and characteristics of the product, including high peak output current, input voltage range, capacitive load driving capability, delay time, rise and fall time, supply current, output impedance, high voltage protection, reverse current protection, negative input protection, ESD protection, etc.
The TC4426A, TC4427A, and TC4428A are dual high‑speed power MOSFET driver families from Microchip. They offer a wide input supply range (4.5 V‑18 V), high peak output current (1.5 A), low output impedance (≈70 Ω), and robust latch‑up and ESD protection. The devices are pin‑compatible with earlier TC426/TC427/TC428 parts and are available in space‑saving 8‑pin MSOP, 8‑pin DFN, PDIP, and SOIC packages.
The datasheet provides detailed electrical specifications, temperature characteristics, typical performance curves, and pin descriptions. It also includes application notes such as use in switch‑mode power supplies, line drivers, and pulse‑transformer drives, as well as guidelines for grounding, input hysteresis, and the exposed metal pad for thermal management.
