High-Performance 1EDI2002AS Isolated Gate Driver from Infineon for Robust Industrial Applications
In the demanding landscape of industrial power electronics, the efficiency, reliability, and robustness of switching components are paramount. At the heart of many advanced systems, from motor drives and solar inverters to industrial SMPS and UPS, lies a critical component: the gate driver. Infineon Technologies, a global leader in semiconductor solutions, addresses these stringent requirements with its high-performance single-channel isolated gate driver, the 1EDI2002AS.
This EiceDRIVER™ family component is engineered to provide superior performance in driving IGBTs and MOSFETs. Its core strength lies in its reinforced electrical isolation, which is achieved through an integrated coreless transformer technology. This isolation is crucial for protecting low-voltage control circuits from the high voltages and noisy environments typical in industrial settings, ensuring both system safety and operational integrity.

A key feature of the 1EDI2002AS is its exceptional switching speed and high output current capability. With peak source and sink currents of up to 4.0 A and 8.0 A respectively, it can swiftly charge and discharge the gate capacitances of large power switches. This capability minimizes switching losses, enables higher frequency operation, and improves overall system efficiency. The driver's desaturation (DESAT) detection is a vital protective feature. It actively monitors the collector-emitter voltage of the connected IGBT to detect short-circuit conditions. Upon detection, it initiates a soft turn-off, safely shutting down the power switch to prevent catastrophic failure and enhance system robustness.
Furthermore, the device incorporates advanced Integrated Circuit (IC) functionality that simplifies design and improves reliability. This includes under-voltage lockout (UVLO) protection for both the primary and secondary sides, ensuring the power switch only operates with a sufficient gate voltage, and a ready output signal that provides status feedback to the microcontroller. Its wide operating voltage range and high noise immunity, thanks to its common-mode transient immunity (CMTI) of over 100 kV/µs, make it exceptionally suited for the harsh electrical noise environments found in industrial applications.
The 1EDI2002AS represents a significant leap forward in gate driver technology, offering designers a compact, highly integrated, and reliable solution that simplifies circuit design, reduces component count, and ultimately leads to more robust and efficient industrial power systems.
ICGOODFIND: The 1EDI2002AS stands out as a top-tier solution for designers seeking to enhance the performance and reliability of their industrial power conversion systems, offering a perfect blend of high drive strength, robust protection, and superior isolation.
