SIM6897M

Overview

The SIM6897M is a high-voltage, three-phase motor driver integrated power module (IPM) manufactured by Sanken Electric USA Inc. It integrates control logic and power MOSFETs into a single package to optimize inverter system performance. The device features a 40-DIP LF2971 package with 29 leads, designed for through-hole mounting. It supports a load voltage of 400V and delivers an output current of 5A per phase. The supply voltage range is specified from 13.5V to 16.5V. Operating temperature spans from -30°C to 100°C. The module includes built-in protection circuits such as overcurrent protection, overcurrent limiting, and thermal shutdown.

Feature Summary

• Integrates full-drive functionality including control and power stages for three-phase motors
• Incorporates built-in protection mechanisms against overcurrent, overcurrent limiting, and thermal shutdown
• Utilizes power MOSFET technology for efficient switching and robust operation
• Features CMOS-compatible inputs supporting both 3.3V and 5V logic levels

Applications

• Fan motor drivers
• Three-phase AC motor control systems
• Brushless DC (BLDC) motor applications
• High-voltage inverter power modules

Procurement Notes

Verify the specific suffix or variant code when ordering, as packaging or minor electrical tolerances may differ between production batches. Confirm that the 40-DIP LF2971 footprint matches your PCB design requirements. Ensure compatibility with the required supply voltage range of 13.5V to 16.5V for the control circuitry. Check for RoHS3 compliance if environmental regulations apply to your assembly process. Cross-reference with official Sanken datasheets for any recent updates to pinout definitions or protection threshold values.

Selection Notes

Select the SIM6897M when a compact, fully integrated solution for three-phase motor driving is required. It is suitable for applications needing 400V blocking voltage and 5A continuous output current. Consider this component for designs prioritizing noise reduction and simplified layout due to the integrated pre-driver and bootstrap circuit options. Evaluate thermal management needs given the operating temperature range up to 100°C. Compare against discrete solutions to assess space savings and reliability improvements offered by the IPM architecture.
