BA6289F-E2 Equivalent & Substitute Parts

Part Overview

The BA6289F-E2 is a bipolar motor driver IC manufactured by Rohm Semiconductor, designed for brushed DC motor control applications. This device integrates control and power stage functionality in a compact 8-SOP package, operating across a 4.6V to 15V supply voltage range with 600mA output current capability. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to address application requirements for extended voltage ranges, higher current capacity, or alternative thermal operating conditions while maintaining functional equivalence in half-bridge output configuration and on/off control interface.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA6289F-E2 is determined by the following critical parameters:

• Output configuration must remain half-bridge (2-channel)
• Control interface must support on/off operation
• Package must be 8-SOP form factor for PCB compatibility
• Motor type must be brushed DC
• Function must include fully integrated control and power stage

The BD6231F-E2 qualifies as a substitute based on matching output configuration, interface type, package form factor, and integrated driver function. Substitution is valid when application requirements permit the extended voltage range (6V ~ 32V supply versus 4.6V ~ 15V), higher output current (1A versus 600mA), and wider operating temperature range (-40°C ~ 150°C junction temperature versus -20°C ~ 75°C ambient temperature) of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the BA6289F-E2 and BD6231F-E2 are active production parts with ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts is determined by application voltage and current requirements:

Use BA6289F-E2 when application supply voltage is constrained to 4.6V ~ 15V range and output current requirement does not exceed 600mA.

Use BD6231F-E2 when application requires supply voltage operation above 15V or up to 32V, output current exceeding 600mA up to 1A, or extended operating temperature range to -40°C or above 75°C. The BD6231F-E2 employs Power MOSFET technology versus the bipolar technology of BA6289F-E2, resulting in different thermal and electrical characteristics suitable for higher-power applications.

Frequently Asked Questions (FAQ)

Q: Can BD6231F-E2 be used as a direct replacement for BA6289F-E2 in existing designs?

A: BD6231F-E2 is pin-compatible and functionally equivalent in half-bridge output configuration and on/off control interface. However, the extended voltage range (6V ~ 32V) and higher current rating (1A) of BD6231F-E2 require verification that PCB layout, power supply design, and motor load characteristics are compatible with the substitute part's specifications. The different semiconductor technology (Power MOSFET versus Bipolar) may affect thermal behavior and switching characteristics.

Q: What are the key differences between BA6289F-E2 and BD6231F-E2?

A: The primary differences are supply voltage range (BA6289F-E2: 4.6V ~ 15V; BD6231F-E2: 6V ~ 32V), output current capacity (BA6289F-E2: 600mA; BD6231F-E2: 1A), operating temperature range (BA6289F-E2: -20°C ~ 75°C ambient; BD6231F-E2: -40°C ~ 150°C junction), and semiconductor technology (BA6289F-E2: Bipolar; BD6231F-E2: Power MOSFET).

Q: Are both parts available in the same package?

A: Yes, both BA6289F-E2 and BD6231F-E2 are supplied in 8-SOIC (0.173", 4.40mm Width) package with identical footprint, enabling PCB-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes, both BA6289F-E2 and BD6231F-E2 are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Which part should be selected for low-voltage applications below 6V?

A: BA6289F-E2 is the appropriate selection for applications requiring supply voltage operation below 6V, as BD6231F-E2 minimum supply voltage is 6V. BA6289F-E2 supports operation down to 4.6V supply voltage.
