BA6285AFP-YE2 Equivalent & Substitute Parts

Part Overview

The BA6285AFP-YE2 is a fully integrated motor driver IC manufactured by Rohm Semiconductor, designed for brushed DC motor control applications. It operates across a 4.5V to 24V supply range with 1A output current capability and features a half-bridge configuration with on/off control interface. The device is housed in a 25-HSOP surface mount package with integrated heat tabs.

This part carries a "Not For New Designs" status, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity. Substitute parts must maintain compatibility with the half-bridge output configuration, brushed DC motor control function, and integrated power stage architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BA6285AFP-YE2 are identified based on the following critical parameters that define functional equivalence:

Core Compatibility Criteria:

• Motor type: Brushed DC
• Function: Fully integrated driver with control and power stage
• Output configuration: Half bridge (2)
• Technology: Bipolar or Bi-CMOS
• Current rating: 1A minimum
• Supply voltage range: Overlap with 4.5V ~ 24V
• Load voltage range: Overlap with 4.5V ~ 24V

Substitution Groups:

Group 1 - Direct Functional Equivalent (Through-Hole Alternative): TA7267BP(O) maintains identical output configuration, current rating, and brushed DC motor control function. The primary difference is mounting type (through-hole vs. surface mount) and control interface (parallel vs. on/off). Supply voltage range is narrower (6V ~ 18V), requiring verification for applications below 6V.

Group 2 - Enhanced Capability Substitutes (Surface Mount, Higher Current): TB6549FG(O,EL) and TB6549PG(O) provide higher output current (4.6A vs. 1A) and extended supply voltage range (10V ~ 27V). Both use Bi-CMOS technology with PWM/Serial control interfaces, offering greater flexibility than the original on/off interface. TB6549FG(O,EL) maintains surface mount packaging; TB6549PG(O) uses through-hole DIP packaging.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): TA7267BP(O) is the closest functional equivalent when supply voltage remains within 6V ~ 18V range. This part is active and RoHS compliant. The through-hole mounting requires PCB redesign if surface mount is mandatory. The parallel control interface differs from the original on/off interface and requires firmware or control circuit adaptation.

For Enhanced Performance Applications: TB6549FG(O,EL) and TB6549PG(O) are suitable when higher output current (4.6A) or extended supply voltage range (10V ~ 27V) is required. Both parts are active with RoHS compliance. TB6549FG(O,EL) maintains surface mount compatibility; TB6549PG(O) requires through-hole PCB layout. PWM/Serial control interfaces provide greater flexibility than on/off control but require interface circuit redesign.

Compliance Considerations: All substitute parts maintain RoHS compliance. The BA6285AFP-YE2 is ROHS3 compliant; substitute parts are RoHS compliant. All parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Frequently Asked Questions (FAQ)

Q: Can TA7267BP(O) be used as a direct pin-for-pin replacement? A: No. While TA7267BP(O) maintains identical output configuration and current rating, it uses a different package type (7-SIP through-hole vs. 25-SOP surface mount), different control interface (parallel vs. on/off), and narrower supply voltage range (6V ~ 18V vs. 4.5V ~ 24V). PCB redesign and control circuit modification are required.

Q: What is the key difference between TB6549FG(O,EL) and TB6549PG(O)? A: Both parts share identical electrical specifications (4.6A output, 10V ~ 27V supply, Bi-CMOS technology, PWM/Serial interface). The primary difference is packaging: TB6549FG(O,EL) uses 20-BSOP surface mount; TB6549PG(O) uses 16-DIP through-hole. Select based on PCB layout requirements.

Q: Is the BA6285AFP-YE2 still available for new designs? A: No. The BA6285AFP-YE2 carries "Not For New Designs" status. For new applications, select from active alternatives: TA7267BP(O), TB6549FG(O,EL), or TB6549PG(O).

Q: What happens if my application requires supply voltage below 6V? A: TA7267BP(O) operates minimum 6V; TB6549 variants operate minimum 10V. Only the original BA6285AFP-YE2 supports 4.5V minimum. If sub-6V operation is required, alternative motor driver architectures must be evaluated.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts are RoHS compliant. The original BA6285AFP-YE2 is ROHS3 compliant; substitute parts are RoHS compliant. Both certifications meet current regulatory requirements.

Q: What control interface changes are required when switching to TB6549 variants? A: The original BA6285AFP-YE2 uses on/off control. TB6549FG(O,EL) and TB6549PG(O) use PWM and serial control interfaces. Control circuit redesign is necessary to accommodate these interfaces. Consult device datasheets for specific pin configuration and timing requirements.
