Overview
The BD6712AF-E2 is a fully integrated two-phase fan motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3.5 V to 6.5 V and utilizes Power MOSFET technology for efficient control. The device features an interface type of parallel communication, allowing for straightforward integration into embedded systems. Designed specifically for fan motor applications, it combines control logic with the power stage in a compact package. The component supports operation across standard industrial temperature ranges and is housed in an 8-SOP (Small Outline Package) format suitable for surface mount assembly.
Feature Summary
- Fully integrated control and power stage for simplified circuit design
- Optimized for two-phase fan motor driving applications
- Parallel interface for direct digital control connectivity
Applications
- Fan motor drivers
- WAVE fan motor control systems
- Embedded cooling solutions
Procurement Notes
Verify the specific suffix E-2 against the official ROHM datasheet to confirm pinout compatibility and electrical characteristics. Ensure the ordering information matches the exact part number required for your design, as minor variations may exist between distributors. Confirm RoHS compliance status directly from the manufacturer's documentation before finalizing procurement decisions.
Selection Notes
Select this component when a dedicated two-phase fan driver is required with a low-voltage supply constraint between 3.5 V and 6.5 V. The parallel interface is suitable for microcontrollers that can manage direct signal lines without complex serial protocols. Consider the 8-SOP package size for PCB space limitations and verify thermal requirements for the intended enclosure environment.
Part Context
This part belongs to the broader category of Motor / Motion / Ignition Controllers & Drivers under ROHM's PMIC portfolio. It is distinct from brushed DC motor drivers like the BD6736 series due to its specific two-phase architecture. The BD6712AF-E2 targets niche applications requiring precise phase control for fans rather than general-purpose bidirectional motor movement.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult the official ROHM replacement guide or contact technical support for cross-reference recommendations if this NRND or obsolete part is no longer viable.
