TC649BEUA

Overview

The TC649BEUA is a fan controller manufactured by Microchip Technology, designed for motor and motion control applications. It operates within a supply voltage range of 3 V to 5.5 V and features an output current capability of 5 mA. The device draws a working supply current of 500 uA and supports a maximum operating frequency of 30 Hz. It is housed in an MSOP-8 surface-mount package and functions across a temperature range from 0°C to +85°C.

Feature Summary

• Integrates shutdown and fault detection capabilities for enhanced system protection
• Provides single-channel fan control functionality
• Designed for low-power operation with minimal supply current consumption

Applications

• Fan speed control systems
• Motor driver interfaces
• Motion control circuits

Procurement Notes

Verify the specific suffix 'BEUA' against official Microchip documentation to confirm the exact package type and tape-and-reel or tube configuration. Ensure compatibility with the required operating temperature range of 0°C to +85°C. Confirm that the 500 uA supply current meets the power budget constraints of the target application design.

Selection Notes

Select this component when a single-output fan controller with integrated fault detection is required. Compare against the TC646B series if restart functionality is needed instead of simple shutdown. Verify that the MSOP-8 footprint aligns with the PCB layout and that the 30 Hz frequency limit suits the specific motor or fan application requirements.
