AUIPS6021S Equivalent & Substitute Parts

Part Overview

The AUIPS6021S is a power switch/driver IC manufactured by Infineon Technologies, designed for high-side N-channel switching applications with a 1:1 input-to-output ratio. This component operates at a maximum load voltage of 36V with an output current capacity of 4.3A and an on-resistance (RDS On) of 24mOhm typical. The device features auto restart capability, current limiting, open load detection, and over-temperature protection, making it suitable for automotive-grade applications.

The AUIPS6021S is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AUIPS6021S is determined by strict alignment of the following critical parameters:

• Output Configuration & Type: High-side N-channel switching with 1:1 input-to-output ratio
• Electrical Performance: Maximum load voltage of 36V, output current capacity, and on-resistance characteristics
• Protection Features: Current limiting, open load detection, and over-temperature protection
• Interface & Control: Non-inverting on/off control logic
• Operating Environment: Temperature range of -40°C to 150°C and automotive-grade qualification

The VN750B5TR-E from STMicroelectronics meets these substitution criteria. It maintains the same output configuration, control interface, and protection feature set while providing enhanced electrical performance characteristics suitable for the same application domain.

Parameter Comparison

Engineering Selection Recommendations

The VN750B5TR-E is the manufacturer-recommended substitute for the AUIPS6021S. Both components are designed for automotive applications and maintain compatibility across critical functional parameters including output configuration, control interface, and protection mechanisms.

The AUIPS6021S is classified as obsolete, while the VN750B5TR-E maintains active product status with current manufacturing availability. The VN750B5TR-E is RoHS3 compliant and carries REACH unaffected status, meeting modern regulatory requirements for electronic component procurement.

From a compliance perspective, both components are designated as REACH unaffected and carry EAR99 ECCN classification. The VN750B5TR-E provides enhanced protection features including over-voltage detection in addition to the current limiting, open load detection, and over-temperature protection present in the original design.

Frequently Asked Questions (FAQ)

Q: Can the VN750B5TR-E directly replace the AUIPS6021S in existing designs?

A: Yes. Both components share identical output configuration (high-side N-channel), control interface (non-inverting on/off), input-to-output ratio (1:1), and core protection features (current limiting, open load detection, over-temperature protection). The operating temperature range and maximum load voltage specifications are equivalent.

Q: What are the differences in electrical performance between these parts?

A: The VN750B5TR-E provides higher maximum output current (6A versus 4.3A) and includes over-voltage protection in addition to the protection features of the AUIPS6021S. The VN750B5TR-E specifies a maximum on-resistance of 60mOhm compared to the AUIPS6021S typical value of 24mOhm. Applications requiring the lower on-resistance characteristic of the original part should evaluate thermal and efficiency implications.

Q: Are there package compatibility considerations?

A: The AUIPS6021S uses a D2PAK (TO-263-5) package, while the VN750B5TR-E uses a P2PAK package. Both are surface-mount packages with similar pin configurations (4 leads plus tab). PCB layout modifications may be required to accommodate the different package footprint.

Q: What is the product status difference between these components?

A: The AUIPS6021S is classified as obsolete with no ongoing manufacturing. The VN750B5TR-E is an active product with current inventory availability, ensuring long-term supply chain continuity for new designs and production support.

Q: Are both components suitable for automotive applications?

A: Yes. The AUIPS6021S carries automotive grade designation with AEC-Q100 qualification. The VN750B5TR-E is designed for automotive applications and maintains equivalent operating temperature specifications (-40°C to 150°C junction temperature).
