BA6289F-E2

Overview

The BA6289F-E2 is a reversible motor driver manufactured by Rohm Semiconductor, designed for brush DC motors. It operates within a supply voltage range of 4.5V to 15V and delivers an output current of 1.0A. The device features a compact 8-SOP package with dimensions of 5.0x6.2mm and a thickness of 1.71mm. It supports an operating temperature range from -20°C to 75°C. Key electrical characteristics include a maximum Vcc of 18V and built-in surge absorption diodes.

Feature Summary

• Built-in power save circuit suppresses current consumption during motor idle states
• Integrated thermal shutdown circuit protects against overheating
• Built-in surge absorption diodes enhance circuit robustness

Applications

• Brush DC motor control in consumer electronics
• Reversible motor drive applications requiring low standby current
• Automotive accessories and interior mechanisms

Procurement Notes

Verify component authenticity through authorized distributors as the BA6289F-E2 may be subject to end-of-life status or obsolescence notices. Confirm package marking and datasheet revision levels match project requirements. Ensure thermal management design accounts for the specified junction temperature limits under maximum load conditions.

Selection Notes

Select this component for single-motor reversible applications requiring integrated protection features. The bipolar interface and on/off control simplify driver logic. Consider the 1.0A output limit and 15V supply ceiling when sizing for specific motor loads. The SOP-8 package suits space-constrained PCB layouts.

Part Context

This part belongs to Rohm's BA62xx series of motor drivers, which typically integrate control and power stages. The BA6289F-E2 variant specifically targets reversible DC motor applications with efficiency optimizations. It shares functional similarities with other ROHM drivers like the BA6287F but differs in package and specific pin configurations.

Replacement Considerations

Public confirmed substitute: BD62110JEFJ-E2. Verify pin compatibility and thermal performance before substitution.
