Overview
The TC648VOA is a fan speed controller from the TC648 series, designed for brushless DC motor applications. It operates within a supply voltage range of 3 V to 5.5 V and draws a typical operating current of 500 uA. The device provides an output current capability of 5 mA and functions reliably across a temperature range of 0°C to +85°C. Packaged in an MSOP-8 surface-mount format, it integrates shutdown and over-temperature alert features for enhanced system protection.
Feature Summary
- Integrates automatic shutdown and over-temperature alert mechanisms for thermal management
- Optimized for low-power operation with minimal quiescent current consumption
- Supports direct control of brushless DC motors without external gate drivers
Applications
- Fan speed control in computer peripherals
- Thermal management in home appliances
- Cooling systems in office equipment
Procurement Notes
Verify the specific suffix 'VOA' corresponds to the MSOP-8 package and tube packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure the design accommodates the specified 0°C to +85°C operating temperature range and 3 V to 5.5 V supply voltage constraints for reliable performance.
Selection Notes
Select this component when a compact, low-power solution for single-fan BLDC control is required. The MSOP-8 package suits space-constrained designs. Consider the 5 mA output drive capability against load requirements. Verify compatibility with existing PCB footprint standards for MSOP-8 packages and ensure thermal design supports the specified ambient operating limits.
Part Context
Part of the TC648 family of fan controllers, offering integrated protection features. The 'VOA' designation specifies the commercial temperature grade and MSOP-8 packaging variant within the broader product line. This series targets cost-sensitive applications requiring basic fan regulation and thermal monitoring capabilities.
Replacement Considerations
Check Microchip documentation for pin-compatible alternatives within the TC648 series. Verify if variants like TC648VUA or TC648BEPA offer identical electrical characteristics and package dimensions for direct substitution.
