Overview
The TC642VUA is a fan controller manufactured by Microchip Technology, designed for low-power applications. It operates within a supply voltage range of 3 V to 5.5 V and features a maximum operating temperature of +85°C with a minimum of 0°C. The device draws a quiescent current of 500 uA and provides an output current capability of 5 mA. It is housed in an MSOP-8 surface-mount package and belongs to the TC648 series under the PMIC category.
Feature Summary
- Integrated fault detection and shutdown alert mechanisms for system protection
- Low power consumption suitable for battery-operated or energy-efficient designs
- Compact surface-mount packaging for space-constrained PCB layouts
Applications
- Fan speed control in consumer electronics
- Thermal management in industrial equipment
- Over-temperature alert systems in embedded devices
Procurement Notes
Verify the specific suffix 'VUA' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing board design regarding MSOP-8 footprint and thermal requirements. Cross-reference datasheet specifications for electrical parameters before integration.
Selection Notes
Select this component when a low-quiescent-current fan controller with integrated fault alerts is required. Consider the MSOP-8 package for surface-mount assembly needs. Evaluate the 0°C to +85°C operating range against environmental conditions. Compare against other TC64x variants if different package styles or extended temperature ranges are necessary.
Part Context
The TC642VUA is part of the broader TC64x family of fan controllers from Microchip Technology. This series focuses on providing efficient motor drive solutions with built-in diagnostic features. The VUA variant specifically denotes the MSOP-8 surface-mount package configuration, distinguishing it from through-hole or alternative package options within the same functional family.
Replacement Considerations
Direct substitutes may include other TC642 variants with compatible pinouts such as TC642EUA or TC642CPA, provided package differences are accounted for. Verify electrical specifications and temperature ranges match application requirements before substitution.
