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. Product Advantages - Integrated 3.3 V or 5 V selectable-output LDO: With a load capability exceeding 100 mA, this LDO delivers a stable internal power supply to control circuits and system modules. - Ultra‑high VBS withstand voltage of up to 700 V: Ensures exceptional reliability and ample voltage margin under harsh operating conditions. - Supports multiple package options based on application requirements: SOP28, SOP32 (with LDO), and TSSOP28L. Key Features - High-side floating supply voltage of 700 V - Output peak current: +300 mA / −500 mA - Input logic compatible with 3.3 V, 5 V, and 15 V levels - Built-in dead‑time control and shoot‑through prevention - Integrated VCC/VBS undervoltage lockout (UVLO) - Overcurrent protection and enable control to simultaneously shut down all outputs - FAULT indicator signaling fault conditions - Configurable external pin for fault reset timing - Built-in 3.3 V/5 V LDO with 100 mA load capacity - Package options: SOP28, SOP32, and TSSOP28L Typical Applications Home appliances, three‑phase motor drives, switching power supplies Typical Application Circuit Functional Block Diagram Pin Configuration SOP32 (with LDO) vs. SOP28 (without LDO) Pin Descriptions SOP32 Pin Descriptions Conclusion The AiP21360L is a high‑performance gate driver chip that integrates key features such as a high‑voltage‑tolerant architecture, multiple protection mechanisms, and an LDO regulator. Its highly integrated design simplifies PCB layouts while significantly enhancing the stability and reliability of high‑voltage drive systems. With its robust performance, the AiP21360L is well suited for a wide range of applications, including variable‑frequency home appliances and industrial motor control, providing a one‑stop solution to meet diverse high‑voltage drive system requirements.
