SIM6891M

Overview

The SIM6891M is a high-voltage three-phase motor driver from Sanken Electric, designed for brushless DC and multiphase stepper motors. It integrates power MOSFETs, pre-drive circuits, and bootstrap components into a single package. The device operates with a supply voltage range of 13.5V to 16.5V and supports load voltages up to 400V. It features an output current capacity of 2.5A and utilizes a 40-DIP (LF2971) through-hole package with 29 leads. The operating temperature range spans from -30°C to 100°C.

Feature Summary

• Integrates transistors, pre-drive circuits, and bootstrap diodes with internal current-limiting resistors
• Includes thermal shutdown protection with automatic reset functionality
• Supports CMOS input levels at 3.3V and 5V
• Provides 1500V insulation voltage guarantee

Applications

• Fan motor drivers
• Brushless DC (BLDC) motor control
• Multiphase stepper motor applications

Procurement Notes

Verify the specific manufacturer designation, as sourcing channels may list this component under Sanken Electric Co., Ltd or Sanken Electric USA Inc. Confirm that the package matches the 40-DIP LF2971 specification. Ensure compatibility with the required 400V load voltage and 2.5A output current for your specific motor application before ordering.

Selection Notes

Select the SIM6891M when a highly integrated solution for three-phase motor driving is required. It is suitable for designs needing built-in bootstrap circuits and thermal protection. Consider its 40-DIP package for through-hole mounting requirements. Verify that the 2.5A output current meets the motor's peak demands and that the 400V rating aligns with the system's bus voltage.

Part Context

This component belongs to the SIM6890M series of high-voltage three-phase motor drivers. It is functionally similar to the SIM2602M and SIM6892M, which are listed as parameter-equivalent alternatives in some catalogs. The SIM6891M specifically targets applications requiring integrated power and logic control in a robust DIP package.

Replacement Considerations

Publicly confirmed equivalent part numbers include SIM6892M and SIM2602M. These are identified as parameter-equivalent substitutes within the same product family.
