TC649EUATR

Overview

The TC649EUATR 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 supply current of 400 uA. The device supports an ambient operating temperature range from -40°C to +85°C and is housed in an 8-lead MSOP package with surface-mount installation. It features integrated shutdown and fault detection capabilities.

Feature Summary

• Integrates shutdown and fault detection mechanisms for enhanced system reliability
• Supports speed control functionality for brushless DC motors
• Utilizes low-power architecture suitable for battery-operated devices

Applications

• Fan controllers
• Brushless DC motor drives
• Battery-powered equipment

Procurement Notes

Verify the specific suffix 'ATR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards as indicated in official documentation. Ensure compatibility with the target PCB footprint for the 8-MSOP package before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring precise PWM control for BLDC fans with minimal power consumption. The integrated fault detection simplifies design complexity compared to discrete solutions. Consider the MSOP package constraints regarding thermal dissipation and board space availability during the layout phase.

Part Context

This part belongs to the TC649 series of FanSense™ motor drivers. It shares functional similarities with other variants like the TC649EOA but differs in packaging type. The series is categorized under PMIC and Motor Controllers within Microchip's portfolio.

Replacement Considerations

Direct substitutes include the TC649EOA, which offers identical electrical specifications but utilizes an 8-SOIC package instead of MSOP.
