TC647VPA

Overview

The TC647VPA is a fan controller from the Microchip Technology TC647 series, designed for brushless DC (BLDC) motor applications. It operates within a supply voltage range of 3 V to 5.5 V and features an operating temperature range of -40°C to +85°C. The device utilizes an MSOP-8 surface-mount package and includes integrated fault detection capabilities. It functions as a PWM fan controller with low standby current consumption.

Feature Summary

• Integrated fault detection for system protection
• Supports PWM control for brushless DC fans
• Low power consumption in standby mode

Applications

• Brushless DC fan speed control
• Thermal management systems
• Computer cooling solutions

Procurement Notes

Verify the specific suffix 'VPA' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for MSOP-8 packages. Check for moisture sensitivity levels and reflow soldering profiles prior to assembly. Confirm availability status directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when fault detection is required alongside PWM fan control. Compare against TC647BEUATR for similar functionality in different packaging. Consider thermal requirements and operating voltage ranges relative to the target application. Verify that the MSOP-8 package fits the design constraints compared to through-hole alternatives.

Part Context

Part of the TC647 family of fan controllers. Related variants include TC647BEUATR and TC647BEOA. Shares core control logic with other members but differs in package and specific feature sets like restart capabilities.

Replacement Considerations

TC647BEUATR offers similar functionality in an MSOP-8 package. TC647BEOA provides comparable features in an SOIC-8 package. Verify pinout compatibility before substitution.
