Overview
The TC646BEOA713 is a FanSense™ series fan controller manufactured by Microchip Technology. It operates within a supply voltage range of 3V to 5.5V and supports PWM control methods for single-fan applications. The device features system shutdown capabilities and is designed for surface-mount installation in an 8-SOIC package with a width of 3.90mm. It functions as a low-side pre-driver controller suitable for brushless DC motor applications, operating reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Supports PWM control method for precise fan speed regulation
- Integrates system shutdown functionality for thermal protection
- Designed specifically for single-fan application scenarios
Applications
- Fan controllers
- Brushless DC (BLDC) motor control
- System thermal management
Procurement Notes
Verify the specific suffix '713' indicates tape-and-reel packaging when sourcing. Confirm the active status or end-of-life notifications via official Microchip documentation prior to finalizing procurement plans. Ensure compatibility with the 8-SOIC footprint during component selection.
Selection Notes
Select this component for designs requiring a dedicated PWM fan controller with integrated shutdown logic. Consider the 8-SOIC package dimensions and the 3V-5.5V operating voltage range against system constraints. Evaluate the need for single-fan capacity versus multi-channel requirements before choosing this part over other FanSense™ variants.
Part Context
This component belongs to the TC646B family within Microchip's FanSense™ portfolio. It shares functional similarities with related models like the TC642B and TC648B but is distinct in its specific pinout and feature set optimized for standard fan control tasks. The 'EOA' designation typically denotes the SOIC package and commercial/industrial temperature grade.
Replacement Considerations
Direct substitutes include the TC646BEOA without the reel suffix. Parameter-equivalent alternatives listed in public databases include the TC642BEOA and TC646EUA713. Verify electrical compatibility and package dimensions before substitution.
