Microchip TC4421/TC4422 9A High‑Speed MOSFET Driver Datasheet
The TC4421 and TC4422 are 9 A high‑speed MOSFET driver ICs from Microchip. They support supply voltages from 4.5 V to 18 V and provide fast rise/fall times (30 ns to 180 ns depending on load capacitance). The devices feature low output resistance (typical 1.4 Ω) and can tolerate reverse currents up to 1.5 A.
The datasheet includes detailed electrical characteristics, pin definitions for PDIP, DFN, SO‑220 and SOIC packages, typical performance curves, and recommended layout guidelines. Contact information for Microchip worldwide support centers is also provided. This manual is written in Chinese.
