TC649EOATR

Overview

The TC649EOATR is a PWM fan controller and driver 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 draws a typical operating current of 400 uA. The device features shutdown and fault detection capabilities to enhance system reliability. It is housed in an 8-pin MSOP package with a maximum operating temperature of +85°C and a minimum of -40°C. This component is classified under Fan / Motor Controllers / Drivers and supports surface mount installation.

Feature Summary

Integrates shutdown and fault detection mechanisms for enhanced operational safety
Optimized for low power consumption suitable for battery-operated systems
Supports speed control functionality for brushless DC motors

Applications

PWM fan speed control
Brushless DC motor drivers
System thermal management controllers

Procurement Notes

Verify the specific suffix 'ATR' indicates reel packaging when sourcing. Confirm RoHS compliance status as required by project specifications. Check for End-of-Life notifications or obsolescence warnings from Microchip Technology prior to finalizing procurement plans. Ensure compatibility with existing PCB footprints for the MSOP-8 package.

Selection Notes

Select this component for applications requiring low quiescent current and integrated fault protection in compact designs. Compare against the TC649EUATR variant if tube packaging is preferred over reel. Consider the TC649EOA if through-hole mounting is necessary instead of surface mount technology. Evaluate alternative sensors like the TC650 series if on-board temperature sensing is also required.

Part Context

The TC649EOATR belongs to the TC649 family of fan controllers from Microchip Technology. This series focuses on efficient management of cooling fans in electronic devices. The EOATR designation specifies the MSOP-8 package and tape-and-reel delivery format, distinguishing it from other variants like the EOA (SOIC) or EUATR (MSOP).
