BD6201FS-E2

Overview

The BD6201FS-E2 is a Brushless DC Motor Controller manufactured by ROHM Semiconductor, designed for driving fan motors. It operates within a supply voltage range of 10 V to 18 V and features an SSOP-24 surface-mount package. The device supports a maximum output current of 30 mA and maintains a low operating power supply current of 2.8 mA. It functions effectively across an extended temperature range from -40 °C to +110 °C. The controller integrates logic for sinusoidal commutation and PWM control, utilizing hall sensor inputs to drive external power transistors.

Feature Summary

• Synthesizes optimal driving signals from hall sensor inputs for brushless motor control
• Supports 180-degree sinusoidal commutation logic for smooth operation
• Enables PWM control with upper and lower arm switching capabilities

Applications

• Air-conditioner fan motor control
• 3-phase brushless fan motor systems
• General purpose BLDC motor applications requiring hall sensor feedback

Procurement Notes

Verify the specific suffix E2 against the original design requirements to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the SSOP-24 package dimensions align with the target PCB footprint. Check for any updated lifecycle status notifications from ROHM Semiconductor prior to finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring precise sinusoidal commutation for low-noise fan operation. Ensure the application utilizes hall sensors for position feedback, as the controller relies on these signals for phase synthesis. Verify that the external level shifter and power transistor selection matches the 30 mA output capability and the 18 V maximum supply voltage constraints.

Part Context

This part belongs to the BD6201x series of 3-phase brushless motor controllers from ROHM. It is engineered for pin compatibility with predecessors like the BD62011FS and BD62012FS, facilitating easier upgrades or replacements in existing designs. The series focuses on integrating commutation logic to simplify the driver architecture for fan applications.

Replacement Considerations

The BD62011FS and BD62012FS are documented as pin-compatible alternatives within the same product family.
