Overview
The TC665EUN is a single brushless DC (BLDC) motor controller and driver manufactured by Microchip Technology. It operates within a supply voltage range of 3V to 5.5V and features an I2C interface for digital control. The device utilizes a 10-MSOP package with dimensions of 3.1mm x 3.1mm x 0.95mm. It supports low-side pre-driver output configuration and includes speed control functionality. The component is rated for operation between -40°C and +85°C ambient temperature, with a typical quiescent current of 150µA and an output current capability of 5mA.
Feature Summary
- I2C digital interface for precise speed and direction control
- Integrated low-side pre-driver for BLDC motor applications
- Compact surface-mount packaging suitable for space-constrained designs
Applications
- Fan controllers
- Brushless DC motor speed regulation
- Single-phase motor motion control systems
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for recent Product Change Notifications regarding label or packing changes. Ensure the selected variant matches the required lead frame and marking details for your manufacturing process.
Selection Notes
Select this component when a compact, digitally controlled solution for single BLDC motors is required. The I2C interface allows for simplified wiring compared to analog counterparts. Consider the 10-MSOP footprint for PCB layout constraints. Evaluate the 5mA output drive capability against the gate charge requirements of the external MOSFETs in your power stage design.
Part Context
The TC665 belongs to Microchip's family of motor controllers designed for efficient and reliable operation in consumer and industrial applications. It integrates necessary control logic with driver outputs to simplify system architecture. The device is part of a broader portfolio that includes variants like the TC664, offering flexibility in pinout and feature sets for different motor control needs.
Replacement Considerations
TC665EUNTR is a direct substitute from the same manufacturer. TC664EUN is a parameter-equivalent alternative. MAX6650EUB+ from Analog Devices is also listed as a parameter-equivalent option.
