Overview
The BD62018BFS-E2 is a three-phase brushless fan motor controller manufactured by ROHM Semiconductor. It operates within a supply voltage range of 10 V to 18 V, with a typical operating voltage of 15 V. The device delivers an output current of 15 mA and consumes a quiescent supply current of 2.5 mA. It supports surface mount installation in an SSOP-A-24 package. The component functions reliably across a temperature range from -40 °C to +110 °C.
Feature Summary
- Integrated control logic for three-phase brushless DC fan motors
- Built-in protection mechanisms against overcurrent and thermal overload
- Compatible with standard PWM speed control signals
- Designed for low power consumption in ventilation applications
Applications
- Air conditioner indoor unit fan motors
- Ventilation system cooling fans
- Electronic equipment thermal management modules
Procurement Notes
Verify the complete part number including the suffix E2 to ensure compliance with lead-free and RoHS directives. Confirm the SSOP-A-24 package variant matches the PCB footprint requirements. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications and electrical characteristics before finalizing procurement orders.
Selection Notes
Select this controller for applications requiring precise three-phase commutation of small brushless fans. Ensure the load current does not exceed the 15 mA limit. Verify that the ambient temperature remains within the specified -40 °C to +110 °C operational range. Consider the 2.5 mA standby current for energy efficiency calculations in always-on systems.
Part Context
This component belongs to the BD62018 series of motor controllers designed specifically for fan applications. It integrates gate drivers and control circuits into a single compact package. The series is optimized for cost-effective and reliable operation in consumer electronics and HVAC systems where space constraints and power efficiency are critical design factors.
Replacement Considerations
The BD62014FS-E2 is a documented alternative within the same product family. Both devices share similar three-phase control capabilities and package types. Verify pin compatibility and current ratings when substituting, as the BD62014FS-E2 specifies a 30 mA output current compared to the 15 mA of the BD62018BFS-E2.
