Zhongwei Aixin: Releases Three-Phase Bridge Driver Circuit—AiP21360L
Gate drivers are core components in power conversion and motor control systems, serving as a high-speed, reliable bridge between the control signals and power MOSFETs/IGBTs. In electronic power systems—whether for new‑energy vehicle drive controls, photovoltaic inverters, industrial variable‑frequency drives, or motor control systems—the precise control provided by gate drivers is indispensable.
Product Introduction
The AiP21360L is a three‑phase bridge driver circuit designed for N‑type power MOSFETs and IGBTs. It comprises three independent half‑bridge driver circuits, with input logic compatible with 3.3 V, 5 V, and 15 V levels, and an absolute maximum voltage rating of up to 700 V. The device can simultaneously turn off all six output channels, features built-in shoot‑through prevention and dead‑time control to ensure that the upper and lower bridge arms never conduct at the same time, and includes undervoltage protection circuits for both VCC and VBS. Additionally, it integrates overcurrent protection and provides FAULT indicators to signal undervoltage and overcurrent faults. An optional 3.3 V or 5 V LDO is included to supply power to external MCUs.
