Overview
The BD69740FV-GE2 is a multifunction single-phase full-wave motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 4.3 V to 17 V and supports output currents up to 1.2 A. The device features Microwire bus interface compatibility and includes an integrated 64 Kbit EEPROM for configuration storage. Designed for surface mount applications, it utilizes an SSOP-B-16 package with a maximum power dissipation of 880 mW. The component functions across a temperature range of -40°C to +105°C and supports operating frequencies from 0 Hz to 400 Hz.
Feature Summary
- Integrates a Microwire bus interface for digital control and communication
- Includes built-in 64 Kbit EEPROM for non-volatile parameter storage
- Supports soft start and soft stop functionality for controlled motor acceleration and deceleration
Applications
- Brushless DC (BLDC) motor control in household appliances
- Single-phase fan speed regulation systems
- Motion control modules requiring precise startup characteristics
Procurement Notes
Verify the specific suffix 'GE2' against the manufacturer's current datasheet to confirm pinout and electrical specifications match the design requirements. Note that this component may be subject to end-of-life or not-recommended-for-new-designations; consult official lifecycle status documentation before finalizing procurement plans to ensure long-term availability and support.
Selection Notes
Select this component when a single-phase BLDC driver with integrated memory and serial interface is required. Ensure the application voltage stays within the 4.3 V to 17 V range and that the thermal design accommodates the specified power dissipation limits in the SSOP-B-16 package. Confirm compatibility with Microwire bus protocols used in the system architecture.
Part Context
This part belongs to ROHM's family of motor controllers and drivers, specifically designed for single-phase applications. It falls under the PMIC category and is distinct from multi-phase or high-power industrial drivers. The BD6974 series focuses on compact solutions for consumer electronics and small appliance markets where space efficiency and integrated control features are prioritized.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference data directly with the manufacturer for any alternative components.
