TC649EOA

Overview

The TC649EOA is a FanSense PWM fan controller manufactured by Microchip Technology, designed for brushless DC (BLDC) motor applications. It operates within a supply voltage range of 3 V to 5.5 V and features a low quiescent current of 400 µA. The device is housed in an 8-SOIC package with a width of 3.90 mm and supports surface-mount installation. It functions as a speed controller with a pre-driver low-side output configuration. The component is rated for an operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

Integrated FanSense technology for precise fan speed control
Low quiescent current consumption for energy efficiency
Built-in shutdown and fault detection capabilities

Applications

Brushless DC (BLDC) fan speed control
System thermal management
Computer cooling solutions

Procurement Notes

Verify the specific suffix 'EOA' corresponds to the 8-SOIC tube packaging variant when ordering. Confirm moisture sensitivity level (MSL 1) handling requirements during assembly. Ensure the design supports the 3 V to 5.5 V input range. Check for any recent Product Change Notices regarding labeling or assembly sites. Validate that the 8-SOIC footprint matches the PCB layout specifications.

Selection Notes

Select the TC649EOA for designs requiring integrated FanSense monitoring in a compact SOIC package. Compare against the TC649EUATR if reel packaging is preferred for high-volume production. Consider the TC649VUA if a wider commercial temperature range starting at 0°C is acceptable and tube packaging is desired. Evaluate power dissipation limits based on the 8-SOIC thermal characteristics.

Part Context

The TC649EOA belongs to the TC649 series of fan controllers from Microchip Technology. This family focuses on efficient BLDC motor driving with integrated sensing. The EO suffix specifically denotes the 8-SOIC plastic package variant. It serves as a specialized PMIC solution for managing cooling fans in electronic systems.
