New Combo Chip with Power-Thru Enhances Isolated Gate Driver

Allegro MicroSystems has recently introduced the third product in its High Voltage Power-Thru portfolio, expanding design options for engineers seeking to maximize power efficiency in various applications. The new product, a combination of Allegro’s AHV85000 and AHV85040 isolated gate driver chips, is designed to work in conjunction with external transformers, catering to industries such as solar inverters, charging infrastructures, energy storage systems, and data center power supply units.

This innovative combo chip retains the advantages of Allegro’s renowned gate driver technology, originally developed by Heydey Integrated Circuits in France. However, a key enhancement lies in the relocation of the isolation transformer from internal to external, offering engineers greater flexibility in designing for isolation, power, and layout. This shift enables designers to select the most suitable transformer based on their specific project requirements.

According to Vijay Mangtani, Vice President and General Manager for High Voltage Power at Allegro, the latest addition to the Power-Thru lineup represents a significant milestone for the company. "We are excited to launch our latest solution, providing engineers with enhanced flexibility and freedom to optimize system architecture and power efficiency by eliminating the need for an internal transformer," Mangtani stated. "This release underscores our ongoing commitment to innovation and responsiveness to the evolving needs of our customers and the design community."

The isolated gate driver not only offers increased design flexibility but also caters to applications with diverse isolation requirements. Engineers can now tailor the isolation level, select the most appropriate transformer for their specific needs, and strategically position the isolation barrier within the system. This level of customization empowers designers to fine-tune their solutions for optimal performance and efficiency.
