Overview
The TC647VUATR is a PWM fan controller manufactured by Microchip Technology, designed for precise speed regulation of cooling fans. It operates within a supply voltage range of 3 V to 5.5 V and draws a typical operating supply current of 1 mA. The device supports an extended industrial temperature range from -40°C to +85°C. Housed in an MSOP-8 surface-mount package, it integrates fault detection capabilities to monitor system health. The component is supplied in reel packaging with a factory quantity of 2500 units per reel.
Feature Summary
- Integrates dedicated fault detection circuitry to identify operational anomalies
- Supports pulse-width modulation control for variable fan speed management
- Operates reliably across a wide industrial temperature spectrum
Applications
- PWM fan speed control systems
- Motor and motion controller applications
- Ignition driver circuits requiring fault monitoring
Procurement Notes
Verify the specific suffix 'VU' confirms the MSOP-8 package and temperature grade against official datasheets. Confirm moisture sensitivity level requirements for storage and handling procedures prior to assembly. Ensure the ordering quantity aligns with the standard reel pack size of 2500 units to match factory specifications.
Selection Notes
Select this component when integrated fault detection is required alongside PWM control. Compare against the TC647VOA variant if an SOIC package is preferred instead of MSOP-8. Consider the TC649 series if shutdown functionality is needed in addition to fault detection features.
Part Context
This part belongs to the TC647 family of motor and motion controllers. It is categorized under PMIC power management ICs specifically for fan and motor drivers. The manufacturer lists it as a specialized solution for applications needing both speed control and diagnostic feedback.
Replacement Considerations
TC647VOA (SOIC-8 package variant)
FAQ
Does the TC647VUATR include automatic shutdown features?
No, the TC647VUATR provides fault detection but does not include automatic shutdown; the TC649 series includes shutdown functionality.
What is the maximum operating temperature for this component?
The maximum operating temperature is +85°C.
