BA6209

Overview

The BA6209 is a reversible motor driver IC manufactured by ROHM Semiconductor, designed for controlling brush-type DC motors. It operates within a supply voltage range of 6V to 18V and delivers an output current of up to 1.6A. The device utilizes CMOS technology to ensure low power consumption while supporting parallel logic interfaces. It features two logic inputs that enable three distinct output modes: forward rotation, reverse rotation, and braking. The component is available in through-hole packaging with 10 terminals and functions reliably across an operating temperature range of -20°C to 75°C.

Feature Summary

• Supports forward, reverse, and braking modes via two logic inputs
• Utilizes CMOS technology for robust low-power operation
• Suitable for direct control of brush-type DC motors

Applications

• Brushed DC motor control in consumer electronics
• Reversible actuator systems requiring low-power driving
• Industrial automation components needing simple parallel interface control

Procurement Notes

Verify the specific suffix (e.g., N) against your schematic requirements, as package variations may exist. Confirm availability status directly with authorized distributors, as some listings indicate discontinuation or limited stock. Ensure the selected variant matches your thermal management needs given the 75°C junction limit. Cross-reference pinouts with official ROHM documentation before integration to prevent wiring errors.

Selection Notes

Select this component when a single-chip solution for bidirectional motor control is required without complex PWM circuitry. It is appropriate for applications where moderate current handling up to 1.6A suffices and low standby power is critical. Consider the through-hole mounting requirement if PCB space allows, as surface-mount alternatives may differ in thermal performance.

Part Context

The BA6209 belongs to ROHM's line of dedicated motor driver integrated circuits. It complements other drivers in the series by offering a balance between simplicity and functionality for basic reversible motor tasks. The design focuses on ease of use with standard logic inputs, making it suitable for cost-sensitive applications where advanced diagnostic features are unnecessary.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Engineers should consult ROHM's official replacement guide or contact technical support for verified equivalents that match the 1.6A current rating and 10-pin through-hole configuration.
