TC649VOATR

Overview

The TC649VOATR is a PWM fan controller and driver manufactured by Microchip Technology. It operates within a supply voltage range of 3 V to 5.5 V and functions at temperatures from 0°C to +85°C. The device draws 1 mA of operating current and utilizes an MSOP-8 surface-mount package. It is designed for brushless DC motor applications, providing speed control capabilities with integrated shutdown and fault detection features.

Feature Summary

• Integrates PWM fan control with low-side pre-driver output configuration
• Includes built-in shutdown and fault detection mechanisms for system protection
• Supports parallel interface communication for speed control operations

Applications

• PWM Fan Controllers
• Brushless DC (BLDC) Motor Speed Control
• Motor Motion Controllers

Procurement Notes

Verify the specific suffix 'V' against official Microchip documentation to confirm temperature grade and package variations. Ensure compatibility with MSOP-8 footprint requirements. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring precise PWM fan speed regulation within a 3 V to 5.5 V supply range. Consider the MSOP-8 package size for space-constrained designs. Evaluate the 0°C to +85°C operating temperature window against environmental conditions. Verify that the parallel interface meets system communication needs.
