BA6235F-E2

Overview

The BA6235F-E2 is a brushed DC motor driver manufactured by ROHM Semiconductor, designed for low-voltage applications. It operates within a supply voltage range of 1.8V to 5V and supports an operating temperature range from -20°C to +75°C. The component is housed in an 8-SOP (SMD/SMT) package with a width of 4.40mm. It functions as an electronic governor for speed control, integrating internal reference voltage generation and amplification circuits suitable for compact media player designs.

Feature Summary

• Integrated electronic governor functionality for precise speed regulation of low-voltage DC motors
• Built-in reference voltage generator and current multiplier for stable operation
• Compact surface-mount packaging suitable for space-constrained portable devices

Applications

• Speed control systems for media players
• Low-voltage brushed DC motor drives
• Portable electronic device actuation

Procurement Notes

Verify the current lifecycle status before procurement, as official documentation indicates this product may be obsolete or subject to discontinuation notices. Confirm that the 8-SOP package dimensions match your PCB footprint requirements. Ensure the input voltage supply strictly adheres to the 1.8V to 5V operational limits to prevent device damage. Cross-reference the specific suffix E2 with the manufacturer's latest datasheet to confirm pinout compatibility and any potential revisions in internal circuitry compared to earlier variants.

Selection Notes

Select this component when designing systems requiring integrated speed control for small brushed DC motors within a 5V logic domain. The built-in governor eliminates the need for external PWM controllers, simplifying the schematic. Consider the thermal performance within the SOP-8 package if continuous high-current operation is anticipated. Verify that the application environment remains within the specified -20°C to +75°C temperature range to ensure reliable long-term performance without derating.

Part Context

This part belongs to the BA6235 series of electronic governors produced by ROHM Semiconductor. These ICs are specifically engineered for consumer electronics where simple, cost-effective motor speed management is required. The series typically targets battery-operated devices due to its low voltage compatibility. Understanding the broader family context helps in identifying compatible pin-outs or alternative components within the same manufacturer's portfolio for future design iterations.

Replacement Considerations

Check for direct substitutes within the BA6235 series or other ROHM motor drivers with similar 8-SOP footprints. Verify that any replacement maintains the 1.8V-5V operating range and integrated governor features. Ensure the alternative component is not obsolete if long-term availability is critical.
