Overview
The BD62011AFS-E2 is a three-phase brushless DC motor controller manufactured by ROHM Semiconductor. It operates within a supply voltage range of 10 V to 18 V and supports output currents up to 15 mA. The device functions at frequencies between 16 kHz and 20 kHz, with a maximum power dissipation of 1 W. It is housed in a 24-SSOP-A package and withstands operating temperatures from -40°C to +110°C.
Feature Summary
- Integrated control for three-phase brushless DC motors
- Supports standard fan motor applications
- Designed for surface mount installation
Applications
- Three-phase brushless fan motors
- OA equipment cooling systems
- AV equipment thermal management
Procurement Notes
Verify the specific suffix 'AFS' against the official ROHM datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the SSOP-A24 package dimensions align with the PCB footprint. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement.
Selection Notes
Select this component when driving small three-phase BLDC fans requiring low output current. The wide temperature range suits diverse environmental conditions. Verify that the 18 V maximum supply voltage fits the system architecture. Consider the 1 W power dissipation limit for thermal management in the target enclosure.
Part Context
This part belongs to ROHM's series of motor controllers designed for consumer electronics. It integrates gate drive logic for three-phase commutation. The family targets cost-sensitive applications in office automation and audio-visual devices where compact size and low power consumption are critical.
Replacement Considerations
The BD62011FS is a related variant. Verify if the 'A' prefix indicates a specific package or revision difference. Cross-reference electrical parameters and pin assignments carefully before substitution.
