AUIPS6041S Equivalent & Substitute Parts

Part Overview

The AUIPS6041S is an N-Channel power switch/driver manufactured by Infineon Technologies, designed for high-side switching applications in automotive-grade power management circuits. This component operates across a 6V to 28V load voltage range with a typical on-resistance of 110mOhm and integrates current limiting, open load detection, and over-temperature protection. The AUIPS6041S is classified as obsolete, making identification of functionally compatible alternatives essential for ongoing design support and production continuity.

Engineering Selection Recommendations

The BTS462TATMA1 is the direct substitute for the obsolete AUIPS6041S based on the following engineering criteria:

Functional Equivalence: Both devices share identical output configuration (high-side N-Channel 1:1), interface type (On/Off non-inverting), and package footprint (TO-252-5 surface mount). Pin-to-pin compatibility is established.

Electrical Performance: The BTS462TATMA1 provides superior electrical characteristics with 70mOhm typical on-resistance compared to 110mOhm, and extends the load voltage operating range to 5V ~ 34V, encompassing the original 6V ~ 28V specification.

Compliance & Certification: Both components meet automotive-grade requirements with AEC-Q100 qualification and identical operating temperature range (-40°C to 150°C junction temperature). The BTS462TATMA1 carries RoHS3 compliance and maintains REACH unaffected status.

Product Lifecycle: The AUIPS6041S is obsolete with no ongoing manufacturing support. The BTS462TATMA1 is active with established supply chain availability (4590 pieces in stock) and belongs to Infineon's miniPROFET® series, ensuring long-term design support.

Enhanced Protection: The BTS462TATMA1 integrates over-voltage fault protection in addition to the current limiting and over-temperature protection present in the original device.

Frequently Asked Questions (FAQ)

Q: Can the BTS462TATMA1 directly replace the AUIPS6041S on existing PCBs?

A: Yes. Both components use the TO-252-5 (DPAK) package with identical pinout and footprint. No PCB modifications are required for mechanical or electrical integration.

Q: What are the key differences between these two parts?

A: The BTS462TATMA1 offers lower on-resistance (70mOhm vs. 110mOhm), extended load voltage range (5V ~ 34V vs. 6V ~ 28V), and additional over-voltage fault protection. The AUIPS6041S is obsolete; the BTS462TATMA1 is actively manufactured.

Q: Are there any thermal or current-handling differences?

A: The BTS462TATMA1 specifies a maximum output current of 3.5A. Both devices share the same operating temperature range (-40°C to 150°C junction temperature) and thermal characteristics are determined by the identical package type.

Q: Is the BTS462TATMA1 suitable for automotive applications?

A: Yes. The BTS462TATMA1 carries AEC-Q100 automotive qualification and is designed for automotive-grade power management circuits, matching the original AUIPS6041S automotive classification.

Q: What is the supply status of the BTS462TATMA1?

A: The BTS462TATMA1 is an active product with 4590 pieces currently in stock as new original inventory. The AUIPS6041S is obsolete with no ongoing production.

Q: Are there any interface or control signal differences?

A: No. Both devices use identical On/Off control with non-inverting input logic. Control circuit modifications are not required.
