TC649BEOATR

Overview

The TC649BEOATR is a fan and motor 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 an output current capability of 5 mA. The device functions as a PWM fan controller with integrated shutdown and fault detection capabilities. It supports a wide operating temperature range from -40°C to +85°C and utilizes a SOIC-8 surface-mount package. The component is supplied in a reel format with a factory packaging quantity of 3300 units.

Feature Summary

• Integrates shutdown and fault detection mechanisms for enhanced system reliability
• Designed specifically for brushless DC motor control applications
• Supports PWM fan control functionality with low power consumption

Applications

• Brushless DC motor control systems
• PWM fan speed regulation
• Industrial motion control interfaces

Procurement Notes

Verify the specific ordering suffix 'A' which denotes tape and reel packaging configuration. Confirm that the part status reflects end-of-life or obsolescence warnings provided by the manufacturer. Ensure compatibility with existing PCB footprints for the SOIC-8 package before finalizing procurement decisions.

Selection Notes

Select this component when designing BLDC motor drivers requiring integrated fault protection and shutdown logic. Consider the 5 mA output current limit and 3 V to 5.5 V supply range against load requirements. Evaluate the SOIC-8 package size constraints and thermal performance within the specified -40°C to +85°C operating temperature window.

Part Context

This component belongs to the TC64x series of fan and motor controllers from Microchip Technology. It shares functional similarities with other variants like the TC647B and TC649E, differing primarily in packaging options and specific feature sets such as restart capabilities. It falls under the broader category of PMIC motor drivers.
