BA6208

Overview

The BA6208 is a monolithic reversible motor driver IC designed for controlling bidirectional motors in consumer electronics. It integrates a TTL-compatible logic section and an output power stage capable of delivering up to 100mA typical output current. The device supports forward, reverse, and forced stop operations via direct logic input control. Key electrical parameters include a wide operating supply voltage range of 4.5V to 15.0V and low standby current consumption when inputs are inactive.

Feature Summary

• Integrates built-in motor driving power transistors with surge absorption diodes
• Enables direct control using standard TTL-level logic signals
• Provides automatic braking functionality when both control inputs are high
• Maintains very low standby circuit current during idle states

Applications

• Cassette player motor control systems
• Reversible DC motor applications in consumer electronics
• General purpose bidirectional motor drive circuits

Procurement Notes

Verify the specific manufacturer source as multiple vendors produce this part number. Confirm package type and pinout compatibility with existing PCB layouts. Check RoHS compliance status if required by regional regulations. Ensure logic level requirements match the system's microcontroller or control interface specifications.

Selection Notes

Select this component for low-current reversible motor applications requiring simple TTL logic control. It is suitable where integrated braking and surge protection reduce external component count. Consider the 100mA output limit when sizing for motor load requirements. Verify thermal performance within the specified operating temperature range.

Part Context

This IC belongs to ROHM's family of simple reversible motor drivers. It serves as a cost-effective solution for basic bidirectional motor control tasks in compact electronic devices. The design emphasizes ease of integration through direct logic interfacing and minimal external circuitry requirements.

Replacement Considerations

BA6208F is a variant with identical functionality but potentially different packaging or suffix designation. Cross-reference with other manufacturers' reversible motor drivers only if pinouts and electrical characteristics are verified to be compatible.
