Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA6285FS-E2 is determined by the following critical parameters: brushed DC motor drive capability, half-bridge (2) output configuration, fully integrated control and power stage function, and compatibility within the specified voltage and current operating ranges. The substitute parts are grouped based on these functional equivalencies while accounting for differences in interface control method, technology platform, and packaging format.

Key substitution criteria:

• Motor type: Brushed DC
• Output configuration: Half Bridge (2)
• Function: Fully integrated driver with control and power stage
• Supply voltage overlap with 4.5V ~ 15V range
• Output current capability of 1A or greater
• Fully integrated architecture

Parameter Comparison

Engineering Selection Recommendations

TA7267BP(O) provides the closest functional match to the BA6285FS-E2 with identical 1A output current and overlapping voltage supply range (6V ~ 18V encompasses the 4.5V ~ 15V requirement). Both devices employ bipolar technology and fully integrated driver architecture. The primary trade-off is the shift from on/off interface to parallel control interface and from surface mount to through-hole packaging. This substitute is suitable for applications where through-hole mounting is acceptable and parallel control signaling can be accommodated.

TB6549FG(O,EL) and TB6549PG(O) represent higher-performance alternatives with 4.6A output current capability and Bi-CMOS technology. These parts operate at higher voltage ranges (10V ~ 27V) and feature advanced PWM and serial interface options. The TB6549FG(O,EL) maintains surface mount packaging, while TB6549PG(O) uses through-hole DIP format. Both are active products with current RoHS compliance. Selection of these parts is appropriate when higher current delivery or extended voltage operation is required.

All substitute parts maintain active product status and full RoHS compliance, ensuring long-term availability and regulatory alignment for new designs.

Frequently Asked Questions (FAQ)

Q: Can TA7267BP(O) directly replace BA6285FS-E2 in existing designs?

A: Functional replacement is possible if the application can accommodate the interface change from on/off to parallel control and the transition from surface mount to through-hole packaging. Voltage and current specifications are compatible within the operating range.

Q: What is the primary difference between TB6549FG(O,EL) and TB6549PG(O)?

A: Both parts share identical electrical specifications (10V ~ 27V supply, 4.6A output, Bi-CMOS technology, PWM/Serial interface). The difference is packaging: TB6549FG(O,EL) is surface mount (20-BSOP with heat tabs), while TB6549PG(O) is through-hole (16-DIP).

Q: Why does BA6285FS-E2 have "Not For New Designs" status?

A: This designation indicates the part is in end-of-life phase. Active alternatives such as TA7267BP(O), TB6549FG(O,EL), and TB6549PG(O) are recommended for new product development.

Q: Are all substitute parts RoHS compliant?

A: Yes. BA6285FS-E2 is ROHS3 compliant, and all substitute parts (TA7267BP(O), TB6549FG(O,EL), TB6549PG(O)) are RoHS compliant, meeting regulatory requirements for both legacy and new designs.

Q: What is the voltage overlap between BA6285FS-E2 and substitute parts?

A: BA6285FS-E2 operates at 4.5V ~ 15V. TA7267BP(O) covers 6V ~ 18V (overlap: 6V ~ 15V). TB6549FG(O,EL) and TB6549PG(O) operate at 10V ~ 27V (overlap: 10V ~ 15V). Applications requiring operation below 6V must use BA6285FS-E2 or verify compatibility with lower voltage limits.

Q: Can TB6549 series parts be used in 1A applications?

A: Yes. TB6549FG(O,EL) and TB6549PG(O) are rated for 4.6A output current, which exceeds the 1A requirement of BA6285FS-E2. These parts are suitable for 1A applications with additional current headroom.
