Overview
The TC654EUN is a Microchip Technology integrated circuit designed as a BLDC motor driver and speed controller. It operates on a supply voltage range of 3V to 5.5V and utilizes an I2C interface for communication. The device features a low-side pre-driver output configuration with two channels, suitable for driving brushless DC motors. It is housed in a 10-MSOP (10-TFSOP) surface-mount package with a width of 3.00mm. The component supports an operating temperature range from -40°C to +85°C and is currently classified as a last-sale item.
Feature Summary
- I2C serial interface enables digital control of motor speed and operational parameters
- Integrated low-side pre-driver architecture simplifies external gate drive requirements
- Optimized for brushless DC (BLDC) motor applications with dedicated speed control functionality
Applications
- Fan speed controllers
- Brushless DC motor management systems
- Industrial automation motor control units
Procurement Notes
Verify the current lifecycle status carefully, as this part is designated as a last-sale item by the manufacturer. Confirm that the 10-MSOP package dimensions align with existing PCB footprints. Ensure I2C address configurations match system requirements before finalizing procurement plans due to limited future availability.
Selection Notes
Select this component when a compact, digitally controlled solution for BLDC motors is required. The I2C interface reduces pin count compared to parallel control methods. Verify that the 3V to 5.5V supply range matches the system power rails. Consider the 10-MSOP package size constraints during mechanical design integration.
Part Context
This component belongs to the TC654 family of motor drivers manufactured by Microchip Technology. It is specifically engineered for applications requiring precise digital control of brushless DC motors. The device integrates necessary control logic with pre-driver outputs, reducing the need for external discrete components in motor control circuits.
Replacement Considerations
Check for official Microchip replacement recommendations or updated series parts. Evaluate alternative BLDC drivers with compatible I2C interfaces and similar package footprints if redesign is necessary.
