Overview
The TC646BEPA is a fan controller manufactured by Microchip Technology, designed for motor and motion control applications. It operates within a supply voltage range of 3 V to 5.5 V and draws a working supply current of 200 uA. The device features an output current capability of 5 mA and supports through-hole installation in an 8-pin PDIP package. It functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates restart, shutdown, and fault detection capabilities for enhanced system reliability
- Optimized for low power consumption with minimal quiescent current draw
- Supports single-fan control architectures with dedicated driver outputs
Applications
- Desktop computer cooling systems
- Server and storage enclosure thermal management
- Industrial equipment ventilation control
Procurement Notes
Verify the specific suffix BEPA confirms the PDIP-8 through-hole package variant. Confirm RoHS compliance status via official documentation before integration. Check for end-of-life notifications or discontinuation notices from Microchip Technology to ensure long-term availability for production cycles.
Selection Notes
Select this component when through-hole mounting is required for mechanical stability or existing PCB footprints. Choose over surface mount variants like TC646BEUA if automated SMT assembly is not available. Ensure the 5 mA output current meets the drive requirements of the connected fan load.
Part Context
This part belongs to the TC646B series of fan controllers, which are specialized integrated circuits for managing brushless DC fans. The TC646BEPA specifically denotes the through-hole PDIP-8 packaging option within this family, distinguishing it from surface-mount MSOP or SOIC alternatives.
Replacement Considerations
TC646BEUA serves as a functional equivalent with identical electrical characteristics but utilizes an MSOP-8 surface-mount package. Verify pinout compatibility and physical footprint differences during substitution planning.
