SIM6811M

Overview

The SIM6811M is a high-voltage, fully integrated three-phase motor driver IC manufactured by Sanken Electric. Designed for brushless DC (BLDC) motors, it features a PowerDIP-40 package with through-hole mounting. Key electrical specifications include a maximum collector-emitter voltage of 500 V and a typical switching frequency of 20 kHz. The device supports a maximum operating supply voltage of 400 V and provides an isolation rating of 1500 Vrms. It operates within a temperature range of -20 °C to +100 °C.

Feature Summary

• Fully integrated control and power stage for three-phase BLDC motor applications
• High voltage capability with 500 V / 600V rated blocking voltage
• Integrated isolation barrier rated at 1500 Vrms for safety compliance
• Robust thermal performance supporting operation up to +100 °C

Applications

• Brushless DC (BLDC) motor control systems
• Industrial automation drives
• High-voltage motor driver modules

Procurement Notes

Verify the specific suffix or variant against the official Sanken Electric datasheet to ensure compatibility with your voltage requirements (500V vs 600V). Confirm that the 40-PowerDIP module package aligns with your PCB footprint and thermal management strategy. Ensure the design accommodates the 1500 Vrms isolation requirements for your application's safety standards.

Selection Notes

Select this component when a fully integrated solution for high-voltage BLDC motors is required. The 40-pin DIP package facilitates prototyping and through-hole assembly. Consider the 500 V/600V rating relative to your bus voltage and the 20 kHz switching frequency for noise and efficiency trade-offs. Verify that the -20 °C to +100 °C operating range meets your environmental constraints.

Part Context

The SIM6811M belongs to Sanken Electric's family of high-voltage three-phase motor driver ICs. It is functionally related to the SIM6813M and SIM6811 series, offering integrated gate drivers and power MOSFETs in a single module. This integration reduces board space and simplifies the design of complex motor control circuits compared to discrete solutions.

Replacement Considerations

Check for direct pin-compatible substitutes within the SIM6811/SIM6813 series from Sanken Electric. Verify that any alternative maintains the same 40-PowerDIP package and 500 V/600V voltage ratings. Cross-reference electrical characteristics such as switching frequency and isolation voltage to ensure functional equivalence.
