BM63964S-VC

Overview

The BM63964S-VC is a 600V, 15A Intelligent Power Module (IPM) designed for three-phase DC/AC inverter applications. It integrates high-side and low-side IGBTs with gate drivers, bootstrap diodes, and protection circuits. The module features an open emitter low-side IGBT design and supports AC 100-240Vrms input voltages. Key electrical characteristics include a collector-emitter saturation voltage of approximately 1.7V and a forward voltage of 1.5V for the freewheeling diode. It utilizes SOI technology for high-voltage level shifting and includes under-voltage lockout and short-circuit protection.

Feature Summary

• Integrates three-phase DC/AC inverter functions with built-in bootstrap diodes and gate drivers
• Features high-side IGBT drive using SOI process for high-voltage level shifting and current limiting
• Includes low-side IGBT drive with short-circuit protection and control supply under-voltage lockout
• Provides thermal monitoring via analog voltage output through the VOT pin

Applications

• High-speed switching drives for washing machines
• Fan motor control systems
• Three-phase inverter circuits operating within specified voltage ranges

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and electrical ratings. Ensure compatibility with existing gate driver interfaces and thermal management requirements. Confirm RoHS compliance status for the specific manufacturing batch. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate that the selected variant meets the required switching frequency and current load specifications for the target application.

Selection Notes

Select this IPM for applications requiring integrated protection and compact three-phase inversion. Consider the open emitter configuration for simplified low-side sensing. Evaluate thermal performance based on the expected duty cycle and ambient conditions. Compare switching losses against alternative modules if high-frequency operation is critical. Ensure the control supply voltage aligns with the UVLO thresholds specified in the technical documentation.

Part Context

This component belongs to ROHM's BM6396x series of intelligent power modules. These modules are engineered for household appliance motor control, offering a balance of performance and integration. The series typically targets AC mains-powered devices, providing a complete solution for driving three-phase motors without external discrete power components.

Replacement Considerations

BM63967S-VC is a parameter-equivalent alternative within the same series. Verify pin compatibility and electrical specifications before substitution. Other variants in the BM6396x family may offer different current ratings or switching speeds.
