TC655EUN

Overview

The TC655EUN is a brushless DC (BLDC) fan controller manufactured by Microchip Technology. It operates within a supply voltage range of 3V to 5.5V and utilizes an I2C interface for control. The device features a low-side pre-driver configuration with two outputs, designed specifically for speed control applications. It is housed in a 10-MSOP package with dimensions of 0.118 inches (3.00mm) width. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated I2C interface for digital speed control
• Low-side pre-driver architecture with dual outputs
• Optimized for brushless DC motor applications

Applications

• Fan controllers
• Brushless DC motor speed regulation

Procurement Notes

Verify the specific suffix 'EUN' against the official datasheet to confirm the tube packaging variant rather than the tape-and-reel version. Confirm that the component status is End-of-Life as indicated by manufacturer notifications. Ensure compatibility with existing I2C bus configurations before procurement.

Selection Notes

Select this component when an I2C-controlled BLDC driver is required in a compact surface-mount package. Verify that the 3V to 5.5V supply range aligns with the system power rails. Consider the thermal performance within the specified -40°C to +85°C ambient range for the intended enclosure environment.

Part Context

This part belongs to the TC65x series of integrated motor drivers and controllers from Microchip Technology. The series focuses on providing efficient solutions for cooling applications requiring precise digital control via standard communication protocols like I2C.

Replacement Considerations

TC655EUN is listed as a direct substitute for TC655EUNTR.
