Overview
The TC649BEPA is a fan controller and driver manufactured by Microchip Technology, designed for brushless DC (BLDC) motor applications. It operates within a supply voltage range of 3 V to 5.5 V and features an output current capability of 5 mA. The device functions at a working frequency of 30 Hz and consumes a typical operating supply current of 500 uA. It supports shutdown and fault detection functionalities. The component is housed in an 8-pin PDIP package with through-hole mounting style, suitable for industrial environments with an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates shutdown and fault detection capabilities for enhanced system reliability
- Designed specifically for controlling brushless DC motors
- Provides low-power operation with minimal supply current consumption
Applications
- Fan speed control systems
- Brushless DC motor drivers
- Industrial motion control units
Procurement Notes
Verify the specific suffix BEPA to confirm the PDIP package type and through-hole mounting configuration. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm that the 5 mA output current meets the load requirements. Check for end-of-life status as some variants in this series may be discontinued.
Selection Notes
Select the TC649BEPA when a through-hole solution is preferred over surface mount options like the MSOP or SOIC variants. This part is suitable for designs requiring integrated fault detection and shutdown features without external components. Consider the 3 V to 5.5 V supply range for compatibility with standard logic levels.
Part Context
The TC649BEPA belongs to the TC649 family of fan controllers and drivers from Microchip Technology. This series focuses on simple, cost-effective solutions for BLDC motor control. The BEPA suffix denotes the specific PDIP packaging, distinguishing it from surface-mount alternatives such as the TC649EOA or TC649VUA.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation.
