Isolated gate driver portfolio expanded with combo chip

Allegro MicroSystems, Inc. has launched the third product in its High Voltage Power-Thru portfolio. Its two-chip AHV85000 and AHV85040 isolated gate-driver IC solutions work together with external transformers to deliver the freedom to design and maximise power efficiency for clean energy applications, including solar inverters, xEV charging infrastructures and ESS, and data centre power supply units.

Expanding upon the company's existing Power-Thru technology, the new combo chip offers the same benefits found in its existing gate driver technology but relocates the isolation transformer from internal to external. By doing so, its latest Power-Thru IC provides engineers greater design flexibility for isolation, power and layout since they can select the suitable transformer according to their design needs.

"We are excited to launch our latest solution in Allegro's Power-Thru lineup. Engineers now have more flexibility and freedom with the new combo chip to streamline system architecture and maximise power efficiency, thanks to the removal of the transformer," said Vijay Mangtani, vice president and general manager for High Voltage Power at Allegro. "This solution represents another example of our commitment to continued innovation and responsiveness to our customers' and the design community's needs."

The new combo chip isolated gate driver provides extra advantages for applications with different isolation requirements. By enabling greater cost and space optimisation, this industry-first solution creates significantly greater design flexibility, including the capability to select the isolation level, the best fit-for-purpose transformer, and where to put the isolation barrier within the system.
