BM63967S-VA

Overview

The ROHM BM63967S-VA is a high-performance Intelligent Power Module (IPM) designed for high-speed switching motor control applications. It integrates a gate driver, bootstrap diode, IGBTs, and freewheeling diodes into a single package. The module features a three-phase DC/AC inverter configuration with a 600V voltage rating and a continuous current capacity of 30A. It utilizes an open emitter design for the low-side IGBTs and includes built-in protection mechanisms such as under-voltage lockout and short-circuit protection. The device operates within a temperature range suitable for residential appliances like washing machines and fans.

Feature Summary

• Integrates high-side and low-side IGBT drivers with SOI-based high-voltage level shifting for simplified circuit design.
• Includes built-in bootstrap diodes and current limiting functions to eliminate external component requirements.
• Provides comprehensive fault detection including short-circuit protection, thermal shutdown, and under-voltage lockout via a fault output signal.

Applications

• High-speed switching drive for AC100-240Vrms household washing machines
• Motor control systems for household fans and blowers
• Three-phase inverter circuits for residential appliance motors

Procurement Notes

Verify the specific suffix (VA vs VC) against the official datasheet to ensure correct pinout and thermal characteristics. Confirm that the application does not involve automotive equipment, as this series is explicitly designated for non-automotive use. Check for updated revision levels or alternative packages if long-term supply continuity is required for production planning.

Selection Notes

Select this IPM when designing three-phase inverter circuits requiring integrated protection and high-speed switching capabilities. It is suitable for applications where minimizing external components and reducing board space are critical. Ensure the system voltage remains below 400V DC and the load current does not exceed the rated 30A limit under specified thermal conditions.
