Overview
The TC665EUNTR is a single-phase brushless DC (BLDC) motor controller and driver manufactured by Microchip Technology. It operates on a supply voltage range of 3V to 5.5V and utilizes an I2C interface for communication. The device is housed in a 10-MSOP package with dimensions of 3.00mm width. It supports an operating temperature range from -40°C to +85°C ambient temperature. The component features a low-side pre-driver output configuration designed for driving external N-MOS/N-P-MOS transistor pairs.
Feature Summary
- I2C serial interface for digital control and status monitoring
- Integrated low-side pre-driver stage for external power switching
- Designed specifically for single-phase BLDC motor applications
Applications
- Fan speed control systems
- Single-phase BLDC motor drives
- Small appliance motor control
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure correct operational characteristics. Check current lifecycle status as components may reach end-of-life. Ensure compatibility with existing I2C bus voltage levels and logic thresholds before integration.
Selection Notes
Select this component for designs requiring precise digital control of single-phase BLDC motors via I2C. It is suitable for applications needing a compact surface-mount solution with integrated pre-driving capabilities. Consider thermal performance within the specified ambient temperature range during PCB layout.
Part Context
This part belongs to the TC66x family of motor controllers from Microchip Technology. These devices are engineered to simplify BLDC motor implementation by combining control logic with driver stages. The family targets cost-sensitive and space-constrained embedded motor control applications.
Replacement Considerations
TC665EUN is the tube-packaged equivalent. TC664EUN is a parametrically similar alternative within the same family. MAX6650EUB+ is listed as a parameter-equivalent substitute from Analog Devices.
