Overview
The TC647BEOATR 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 a low operating supply current of 200 uA. The device provides an output current capability of 5 mA and functions as a low-side pre-driver. It supports speed control functionality and includes restart and fault detection features. The component is housed in an 8-SOIC surface-mount package and is rated for operation across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates restart and fault detection mechanisms for enhanced system reliability
- Functions as a dedicated fan controller with speed control capabilities
- Utilizes a low-side pre-driver output configuration for BLDC motors
Applications
- Brushless DC (BLDC) motor speed control
- Fan controller circuits
- Motor motion systems requiring fault detection
Procurement Notes
Verify the specific suffix 'EOA' corresponds to the SOIC-8 package variant when sourcing replacements. Confirm end-of-life status, as official notices indicate discontinuation around May 2026. Ensure compatibility with existing PCB footprints for 8-SOIC packages during design updates. Check moisture sensitivity levels and storage conditions prior to assembly.
Selection Notes
Select this component for designs requiring integrated fault detection and restart logic in fan control applications. Consider the 200 uA quiescent current for power-sensitive projects. Evaluate the 8-SOIC package constraints against available board space. Compare against other FanSense series variants if different package types or additional protection features are required.
Part Context
This part belongs to the TC647B series from Microchip's FanSense family. It is categorized under Motor / Motion / Ignition Controllers & Drivers within the PMIC segment. The device shares functional similarities with related models like the TC642B but is distinguished by its specific feature set including restart and fault detection capabilities tailored for cooling applications.
Replacement Considerations
Direct equivalent: TC647BEOA. Parameter equivalent options include TC647VOATR and TC647VUATR, though these may differ in package type or specific feature sets such as shutdown modes.
