Key Parameters

Substitute Part Grouping Explanation

Substitution of the IPS7091STRLPBF is determined by the following critical parameters:

Package Compatibility: The substitute must use the same D2PAK (TO-263-5) surface mount package to ensure PCB layout compatibility without redesign.

Output Configuration: The substitute must maintain high-side switching topology with non-inverting input control.

Electrical Operating Range: The substitute must support the load voltage range of 6V to 35V minimum, with operating temperature range of -40°C to 150°C.

Current Handling: While the IPS7091STRLPBF is rated for 1.5A maximum output current, substitutes with higher current ratings remain compatible for this application, provided all other parameters align.

Thermal and Compliance: The substitute must maintain MSL 1 rating and REACH compliance status for manufacturing and environmental requirements.

The BTS441RGATMA1 meets all substitution criteria through identical package configuration, matching output topology, expanded voltage range (4.75V ~ 43V), superior current capability (17A), and active product status with full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The BTS441RGATMA1 is the qualified substitute for the obsolete IPS7091STRLPBF based on the following engineering criteria:

Package and Pinout Compatibility: Both devices use the D2PAK (TO-263-5) package, enabling direct PCB footprint compatibility without layout modifications.

Functional Equivalence: Both devices provide single-channel high-side power switching with non-inverting input control, maintaining identical circuit topology and control interface requirements.

Electrical Performance: The BTS441RGATMA1 exceeds the electrical specifications of the IPS7091STRLPBF across all critical parameters. The expanded voltage range (4.75V ~ 43V versus 6V ~ 35V) and increased current rating (17A versus 1.5A) provide enhanced design margin and future application flexibility. The reduced on-resistance (15mOhm versus 80mOhm) improves thermal efficiency.

Product Status and Support: The BTS441RGATMA1 holds active product status with full manufacturing support, ensuring long-term availability and supply chain continuity. The device includes advanced protection features (status flag, current limiting, open load detection, over-temperature, over-voltage) not specified in the legacy IPS7091STRLPBF.

Compliance and Environmental: Both devices maintain MSL 1 rating and REACH compliance. The BTS441RGATMA1 additionally provides ROHS3 compliance certification, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the BTS441RGATMA1 be used as a direct replacement for the IPS7091STRLPBF without PCB modifications?

A: Yes. Both devices use identical D2PAK (TO-263-5) packaging with the same pinout configuration, enabling direct substitution without PCB layout changes.

Q: What is the impact of the higher current rating (17A) of the BTS441RGATMA1 on applications designed for 1.5A?

A: The higher current rating does not negatively impact existing applications. The BTS441RGATMA1 will operate safely at 1.5A or lower. The increased rating provides design margin and allows for future application expansion without component change.

Q: Are there differences in control interface or signal requirements between these devices?

A: No. Both devices use non-inverting input control with identical logic levels and switching behavior. No firmware or control circuit modifications are required.

Q: How does the reduced on-resistance (15mOhm versus 80mOhm) affect thermal performance?

A: The lower on-resistance of the BTS441RGATMA1 reduces power dissipation during switching operation, resulting in lower junction temperatures and improved thermal efficiency compared to the IPS7091STRLPBF.

Q: What is the significance of the expanded voltage range (4.75V ~ 43V) of the BTS441RGATMA1?

A: The expanded range provides compatibility with a broader set of supply voltages. Applications operating within the original 6V ~ 35V range remain fully compatible, while the extended range enables use in additional voltage domains.

Q: Are there any supply chain or availability considerations for the BTS441RGATMA1?

A: The BTS441RGATMA1 maintains active product status with established manufacturing and distribution channels. The IPS7091STRLPBF is obsolete and subject to limited availability. Transition to the BTS441RGATMA1 ensures long-term supply security.

Q: Do the advanced protection features of the BTS441RGATMA1 (status flag, current limiting, open load detection) require additional circuit design?

A: These features are integrated into the device and operate automatically. Existing circuit designs require no modifications to benefit from these protections. Optional status flag monitoring can be implemented if desired for enhanced system diagnostics.
