TC642BEOA

Overview

The TC642BEOA is a FanSense™ series motor controller and driver manufactured by Microchip Technology. Designed for brushless DC (BLDC) motors, it operates within a supply voltage range of 3V to 5.5V and supports an operating temperature range of -40°C to +85°C. The component is housed in an 8-SOIC package with a width of 3.90mm. It features low-side pre-driver outputs and includes integrated restart and fault detection capabilities.

Feature Summary

• Integrates restart and fault detection mechanisms for enhanced system reliability
• Optimized for speed control applications in fan and BLDC motor systems
• Supports parallel interface communication for simplified integration

Applications

• Fan controllers
• Brushless DC motor speed control
• Motion control systems

Procurement Notes

Verify the current lifecycle status as the manufacturer has indicated end-of-life planning. Confirm compatibility with existing PCB footprints and signal levels before procurement. Check for alternative packaging options such as tape and reel if available. Ensure that the specific suffix matches the required quantity format for production runs.

Selection Notes

Select this component for applications requiring integrated fault management and restart logic in low-voltage motor drives. Consider the 8-SOIC package constraints for board space. Evaluate the need for external components based on the low-side output configuration. Compare against other FanSense™ variants for feature alignment.

Part Context

Part of the TC642 family, which focuses on intelligent motor control solutions. The TC642BEOA variant specifically adds restart and fault detection functionalities compared to basic drivers. It belongs to the broader PMIC category under motor controllers and drivers within Microchip's portfolio.

Replacement Considerations

TC642EOA713 is listed as a parameter equivalent substitute. Verify pinout and functional compatibility before substitution.
