Zhongwei Aixin: Releases the Three-Phase PNMOS Gate Driver AiP4480
Gate drivers are critical core components in power conversion and motor control systems, serving as a high-speed, reliable interface between the control signals and the power MOSFETs or IGBTs. In power electronic systems—whether in new‑energy vehicle drive controls, photovoltaic inverters, industrial variable‑frequency drives, or motor control systems—their performance hinges on the precise control provided by gate drivers.
Product Introduction
The AiP4480 is a high-speed, high-performance three-phase P/NMOS gate‑drive IC capable of reliably driving power devices such as MOSFETs and IGBTs. Its logic inputs are fully compatible with both CMOS and TTL signals, and its primary function is to convert low‑voltage logic levels into high‑voltage drive outputs. Throughout the full operating voltage range, it exhibits stable AC and DC electrical characteristics.
Product Advantages
- Ultra-low static power consumption: with a quiescent current of less than 1 mA, it effectively reduces system power draw and is well suited for low-power, portable applications.
- Integrated 5V LDO with a 60mA load capability: Provides power to the MCU and other board-level circuits, reducing the number of components required and simplifying system wiring.
- Integrated over-temperature protection: The system self‑monitors its temperature; when an over‑temperature condition is detected, it promptly shuts down and locks the output. Once the temperature returns to normal, the lock is released, ensuring reliable operation under all operating conditions.
- Compatible with mainstream package types, supporting various form factors such as SOP16, TSSOP16, and QFN16.

Conclusion
The AiP4480 is a high‑performance three‑phase P/NMOS gate‑driver IC that specifically addresses key industry challenges, including insufficient drive headroom, elevated switching losses, poor inter‑phase synchronization accuracy, and inadequate stability under harsh operating conditions. The chip supports a wide supply voltage range of 6 to 36 V, making it suitable for a broad array of applications, such as industrial control systems, consumer power supplies, and motor drives, while maintaining stable electrical performance across the entire voltage range. Featuring high‑current drive outputs, it enables fast switching of power MOSFETs and IGBTs, and incorporates comprehensive built‑in protection features—including latch‑up immunity, EMI suppression, undervoltage lockout, and thermal shutdown. As a result, it delivers outstanding overall performance in three‑phase drive synchronization, load‑drive capability, response speed, and long‑term system reliability.
