Overview
The VLA555-01R is a hybrid integrated circuit designed as a dual IGBT gate driver with an isolated DC/DC converter. It features a peak output current of ±24A and supports a main circuit voltage up to 840V. The device provides electrical isolation of 4000 Vrms and includes built-in short circuit protection with soft shutdown, a collector clamp circuit, and CMOS-compatible input interface.
Feature Summary
- Directly mountable on the New Mega Power Dual package
- Built-in isolated DC/DC converter for gate drive
- Integrated short circuit protection with soft shutdown
- Built-in collector clamp circuit
Applications
- Gate Driver for 1200V New Mega Power Dual IGBT Modules
- Gate Driver for 1700V New Mega Power Dual IGBT Modules
Procurement Notes
Verify that the specific part number matches the required main circuit voltage rating, as the -01R variant is rated for 840V while the -02R is rated for 1200V. Confirm compatibility with the target IGBT module series, such as the CM2500DY-24S, before procurement. Ensure the supply voltage and optical fiber interface components align with the application requirements.
Selection Notes
Select this component when driving IGBT modules in the New Mega Power Dual package. The -01R version is suitable for applications requiring a maximum main circuit voltage of 840V. Consider the integrated DC/DC converter and protection features to simplify the design of high-reliability systems requiring galvanic isolation and robust fault handling.
Part Context
This component belongs to the VLA555 series of dual IGBT gate drivers manufactured by Powerex Inc. It is specifically engineered to interface with the company's New Mega Power Dual IGBT modules, providing a compact solution for high-power switching applications with integrated power conversion and signal isolation.
Replacement Considerations
The VLA555-02R is a related variant within the same series but is rated for a higher main circuit voltage of 1200V compared to the 840V limit of the VLA555-01R. Verify voltage ratings when substituting.
