Overview
The BD6721FS-E2 is a single-phase full-wave motor driver designed for fan motors, manufactured by ROHM Semiconductor. It operates within a supply voltage range of 4.5 V to 17 V and supports an output current of up to 1 A. The device utilizes DMOS technology and accepts PWM input signals for speed control. It is housed in a 16-pin SSOP-A16 package with dimensions of 6.6 mm x 6.2 mm and a height of 1.71 mm. The component functions reliably across an operating temperature range from -40 °C to +100 °C.
Feature Summary
- Integrates a half-bridge configuration for single-phase full-wave motor driving applications
- Supports PWM soft switching for controlled motor operation
- Includes fault detection capabilities via FG/AL signal outputs
Applications
- Fan motor control systems
- Video projector cooling mechanisms
- Personal computer peripheral thermal management
Procurement Notes
Verify the specific ordering suffix, as the BD6721FS-E2 designation indicates the RoHS-compliant version of the BD6721FS series. Confirm that the SSOP-16 package matches the target PCB footprint requirements. Ensure design compatibility with the 4.5 V to 17 V supply voltage window and the 1 A maximum output current limit before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring a dedicated single-phase driver with integrated protection features. The inclusion of FG/AL signals allows for monitoring operational status. Consider the thermal performance within the specified -40 °C to +100 °C range when designing the heat dissipation strategy for the SSOP-16 package.
Part Context
This part belongs to the BD6721 series of motor drivers produced by ROHM Semiconductor. It is specifically engineered for quiet operation in fan motor applications. The product line focuses on providing reliable motion control solutions with integrated safety features for consumer electronics and office equipment.
Replacement Considerations
The BD61245EFV is listed as a recommended replacement with similar specifications. Note that the substitute uses an HTSSOP-B16 package, which differs physically from the original SSOP-A16 form factor. Verify pinout compatibility and voltage tolerances before substitution.
