TC654EUNTR

Overview

The TC654EUNTR is a dedicated motor driver integrated circuit manufactured by Microchip Technology, designed for controlling brushless DC (BLDC) fans. It operates within a supply voltage range of 3V to 5.5V and utilizes an I2C interface for digital speed control. The device features a low-side pre-driver output configuration with two outputs. It is housed in a 10-MSOP surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

I2C digital interface enables software-controlled fan speed management without external microcontroller complexity.
Integrated low-side pre-driver architecture specifically optimized for driving BLDC fan motors.
Supports operation across industrial temperature ranges suitable for diverse electronic equipment environments.

Applications

Fan controller applications
Brushless DC (BLDC) motor speed regulation

Procurement Notes

Verify the specific suffix 'EUNTR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 10-MSOP footprint matches the target PCB design guidelines. Ensure the component meets RoHS3 compliance standards if mandated by the end-product environmental regulations.

Selection Notes

Select this component when a compact, digitally controlled solution for BLDC fan speed regulation is required. The I2C interface simplifies system integration compared to analog alternatives. Consider the 10-MSOP package size constraints and the specific voltage requirements of the target motor load before finalizing the design.

Part Context

This part belongs to the TC65x family of motor drivers. While other variants like the TC652/TC653 integrate temperature sensing, the TC654 focuses purely on digital motor control via I2C. It serves as a specialized power management IC for cooling systems in modern electronics requiring precise fan speed adjustment.

Replacement Considerations

Check for availability of the cut-tape variant TC654EUNCT or the Digi-Reel option TC654EUNDKR if reel quantities are unsuitable. Verify pinout compatibility with any legacy designs using similar MSOP packages.
