Overview
The TC648VUA is a fan controller 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 consumes a typical operating supply current of 500 uA. The device features an output current capability of 5 mA and functions reliably across an operating temperature range from 0°C to +85°C. Housed in an 8-MSOP surface-mount package, it integrates shutdown and over-temperature alert capabilities for enhanced system protection.
Feature Summary
- Integrates shutdown and over-temperature alert functionality for thermal management
- Designed specifically for fan control and BLDC motor driver applications
- Supports low-power operation with minimal supply current consumption
Applications
- Fan speed control systems
- Brushless DC motor driver circuits
- Thermal management units requiring over-temperature alerts
Procurement Notes
Verify the specific suffix 'VUA' against the official Microchip datasheet to confirm package type and temperature grade. Ensure compatibility with the target PCB footprint for the 8-MSOP package. Confirm that the 0°C to +85°C operating range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a dedicated fan controller with integrated thermal protection is required. The 8-MSOP package suits space-constrained designs. Consider the 5 mA output current limit when sizing external drive components. Verify that the 3 V to 5.5 V supply range aligns with the system power architecture. Compare against other TC648 variants if different temperature ranges or packages are needed.
Part Context
The TC648VUA belongs to the TC648 series of fan controllers from Microchip Technology. This series focuses on efficient control of cooling fans and small BLDC motors. The device simplifies design by integrating necessary protection features directly into the controller, reducing the need for external monitoring circuitry in standard thermal management applications.
Replacement Considerations
Direct substitutes include other TC648 series variants such as TC648BEUA or TC648BEOA, provided the package and temperature specifications match the design requirements. Verify electrical parameters and pinout compatibility before substitution.
