Overview
The BD6722FS-E2 is a single-phase DC brushless fan motor driver manufactured by ROHM Semiconductor. It operates within a power supply voltage range of 4.5 V to 17 V, with a maximum Vcc of 20 V and a typical 12 V operation. The device delivers a maximum output current of 1.5 A and supports PWM soft switching for efficient drive control. It features integrated FG/AL signal outputs and functions across an operating temperature range from -40 °C to +100 °C. The component is housed in an SSOP-A16 package measuring 6.6 x 6.2 mm with a thickness of 1.71 mm.
Feature Summary
- Supports direct PWM and DC voltage speed control methods
- Includes built-in current limiting function for protection
- Features PWM soft switched drive capability to reduce noise
- Provides integrated FG and AL signal outputs
Applications
- DC brushless fan motor control systems
- Liquid crystal display (LCD) backlight cooling fans
- Television set internal cooling mechanisms
Procurement Notes
Verify the obsolete status of this specific part number before design finalization. Confirm availability of recommended substitutes such as the BD69730FV-GE2 if production continuity is required. Ensure that the SSOP-A16 package dimensions align with existing board layouts. Check RoHS compliance documentation for regulatory adherence in target markets.
Selection Notes
Select this driver for single-phase BLDC applications requiring up to 1.5 A output current. Consider the wide operating temperature range for environments subject to thermal stress. Evaluate the need for integrated FG/AL signals versus external monitoring solutions. Assess compatibility with existing PWM control interfaces and voltage levels within the 4.5 V to 17 V range.
Part Context
This component belongs to the BD6722FS series of motor drivers designed for fan applications. It integrates NMOS half-pre-driver technology to simplify circuit design. The series focuses on reducing external component count through built-in protection and control features. It serves as a specialized solution for compact cooling systems in consumer electronics.
Replacement Considerations
The BD69730FV-GE2 is listed as a manufacturer-recommended substitute. Verify pinout compatibility and electrical specifications before substitution. Review datasheet differences regarding package type and control interface requirements.
