Overview
The TC649VUA 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 500 uA. The device features a single output capable of sourcing 5 mA and functions at a frequency of 30 Hz. It is housed in an MSOP-8 surface-mount package and supports an industrial operating temperature range from 0°C to +85°C.
Feature Summary
- Integrates shutdown and fault detection capabilities for enhanced system reliability
- Provides dedicated PWM control for efficient fan speed management
- Utilizes low-power architecture suitable for energy-constrained applications
Applications
- Computer cooling systems
- Server and storage enclosure thermal management
- Industrial equipment ventilation control
Procurement Notes
Verify the specific suffix 'VUA' against the official Microchip datasheet to confirm the tube packaging configuration and lead-free status. Ensure compatibility with the required MSOP-8 footprint and check for moisture sensitivity level requirements during assembly. Confirm that the 3V to 5.5V supply range aligns with the target system design specifications before finalizing procurement.
Selection Notes
Select this component when a single-channel PWM fan driver with integrated fault detection is required. Compare the 500 uA supply current against alternatives if ultra-low power consumption is critical. Consider the MSOP-8 package size constraints and the 0°C to +85°C temperature range suitability for the intended environment relative to other TC649 series variants.
Part Context
This part belongs to the TC649 series of fan controllers from Microchip Technology. The series focuses on providing reliable motor and fan drive solutions with integrated protection features. The TC649VUA specifically denotes the commercial temperature grade variant in the MSOP-8 package, distinguishing it from extended temperature or different package options within the same functional family.
Replacement Considerations
Consult the official Microchip TC649 datasheet for confirmed pin-compatible or functionally equivalent substitutes. Verify that any alternative maintains the same MSOP-8 footprint and electrical characteristics.
