Overview
The BA6427F-E2 is a single-phase full-wave fan motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3 V to 14 V and draws an operating supply current of 9 mA. The device supports a minimum operating temperature of -40°C and a maximum of +85°C. Packaged in an 8-SOP surface-mount format, it integrates control and power stages for brushless DC (BLDC) motors.
Feature Summary
- Integrates fully integrated control and power stages for single-phase applications
- Designed specifically for driving brushless DC (BLDC) fan motors
- Supports full-wave drive operation for efficient motor control
Applications
- Brushless DC fan motor control systems
- Single-phase BLDC motor drivers
- Thermal management units requiring integrated motor drive solutions
Procurement Notes
Verify the specific suffix E2 against the official ROHM datasheet to confirm pinout and electrical characteristics match your design requirements. Confirm that the 8-SOP package dimensions align with your PCB footprint constraints. Ensure the operating temperature range of -40°C to +85°C meets your environmental specifications before finalizing procurement.
Selection Notes
Select this component when a single-phase BLDC motor driver is required with an integrated power stage. The 3 V to 14 V input range suits low-voltage applications. Consider the 8-SOP package for space-constrained designs. Verify compatibility with the specific motor's voltage and current demands against the datasheet limits.
Part Context
This part belongs to the ROHM BA64xx series of motor controllers. It serves as a dedicated solution for single-phase fan motors, distinguishing itself from multi-phase stepper or universal motor drivers. The integration reduces external component count compared to discrete driver solutions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult ROHM technical support or authorized distributors for qualified alternatives if this component is unavailable.
