BM63963S-VC

Overview

The BM63963S-VC is a 600V, 10A Intelligent Power Module (IPM) designed for three-phase DC/AC inverter applications. It integrates high-side and low-side IGBTs, gate drivers, bootstrap diodes, and protection circuits within a 25-PowerDIP package. The module supports AC 100-240Vrms input systems with a DC voltage below 400V. Key electrical characteristics include a collector-emitter saturation voltage of 1.5V and an isolation voltage of 1500Vrms. It features open emitter low-side IGBTs and analog temperature output capabilities.

Feature Summary

• Integrates SOI-based high-side gate drivers with built-in bootstrap diodes and current limiting functions.
• Provides short-circuit protection and under-voltage lockout for both high-side and low-side drivers.
• Features open emitter low-side IGBTs to facilitate external current sensing.
• Outputs internal die temperature as an analog voltage signal via the VOT pin.

Applications

• Three-phase motor control for household appliances
• Compressor drive systems
• Fan speed control units

Procurement Notes

Verify component authenticity through authorized ROHM distributors or direct manufacturer channels. Confirm the specific suffix matches the required package variant. Check for recent Product Change Notifications (PCN) regarding manufacturing site updates. Ensure compliance with RoHS3 standards for the target market. Validate that the supply chain documentation aligns with current quality assurance requirements.

Selection Notes

Select this IPM for designs requiring integrated protection without external discrete components. The open emitter configuration allows for precise current monitoring if needed. Consider thermal management requirements based on the 1.5V saturation voltage at rated load. Verify that the control logic interfaces correctly with the 3.3V or 5V input levels supported by the gate drivers.
