Infineon 2EDN7524R: A High-Performance Dual-Channel Isolated Gate Driver IC
The evolution of power electronics demands gate driver ICs that offer not only robust performance but also enhanced integration and safety. Addressing these needs, Infineon Technologies introduces the 2EDN7524R, a state-of-the-art dual-channel isolated gate driver designed to drive MOSFETs and IGBTs in a wide range of high-frequency applications. This driver is particularly suited for use in switch-mode power supplies (SMPS), industrial motor controls, solar inverters, and automotive systems, where efficiency and reliability are paramount.
A standout feature of the 2EDN7524R is its reinforced electrical isolation up to 5 kV RMS, which ensures safe operation in high-voltage environments by protecting low-voltage control circuits from high-power stages. This isolation is achieved through Infineon’s proprietary coreless transformer technology, enabling high noise immunity and reliability while minimizing propagation delay.
The device delivers peak output current of 4 A (source) and 6 A (sink), allowing for rapid switching of power transistors. This strong drive capability reduces switching losses, improves thermal performance, and enhances overall system efficiency. Each of the two independent channels can be configured flexibly, supporting both low-side and high-side operation with typical operating voltages up to 1200 V.
Furthermore, the 2EDN7524R integrates advanced protection features such as under-voltage lockout (UVLO) for both primary and secondary sides, which prevents malfunction during power-up and power-down sequences. The IC’s compact DSO-8 package makes it an excellent choice for space-constrained designs without compromising performance.
With a wide supply voltage range and compatibility with logic-level inputs, the 2EDN7524R ensures easy interfacing with microcontrollers or DSPs. Its high common-mode transient immunity (CMTI) of over 100 kV/µs ensures stable operation even in noisy switching environments.
The Infineon 2EDN7524R sets a high standard for isolated gate drivers with its dual-channel design, high drive strength, and robust isolation. It is an ideal solution for modern power conversion systems that require high switching frequency, safety, and integration in a compact form factor.
