Overview
The TC649VOA is a fan controller manufactured by Microchip Technology, designed for managing cooling systems. 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 operation across a temperature range of 0°C to +85°C.
Feature Summary
- Integrates shutdown and fault detection capabilities for enhanced system protection
- Designed specifically for fan control applications with low power consumption
- Utilizes a compact MSOP-8 surface-mount package for efficient board space utilization
Applications
- Fan speed control in electronic equipment
- Thermal management systems requiring fault detection
- Shutdown logic implementation for cooling fans
Procurement Notes
Verify the specific suffix 'VOA' against the official Microchip datasheet to confirm package type and temperature grade. Ensure compatibility with the target PCB footprint for the MSOP-8 package. Confirm that the 3V to 5.5V supply range aligns with the system design requirements before procurement.
Selection Notes
Select this component when a dedicated fan controller with integrated fault detection is required. Consider the 500 uA supply current for low-power designs. Verify that the single output configuration meets the load requirements of the connected fan. Ensure the operating temperature range of 0°C to +85°C is sufficient for the intended environment.
