AUIPS6041S

AUIPS6041S Description

The AUIPS6041S from Infineon Technologies is a high-side N-channel power switch designed for automotive-grade applications, offering robust performance in demanding environments. This 1:1 ratio device operates with a 6V to 28V load voltage range, making it suitable for 12V/24V automotive systems. Packaged in a D2PAK-5 surface-mount form factor, it integrates a 110mΩ typical Rds(on) MOSFET for efficient power handling. Although marked obsolete, its design ensures reliability with current limiting, open-load detection, and over-temperature protection, alongside an auto-restart feature for fault recovery.

AUIPS6041S Features

• High-Side Configuration: Simplifies wiring by eliminating the need for a low-side driver.
• Automotive Compliance: Meets stringent AEC-Q standards for reliability in vehicles.
• Integrated Protections: Fixed current limiting, open-load detection, and thermal shutdown enhance system safety.
• No Vcc/Vdd Required: Reduces external component count, saving board space.
• Low Rds(on): 110mΩ minimizes conduction losses, improving efficiency.
• Auto-Restart Function: Automatically recovers from transient faults, reducing downtime.

AUIPS6041S Applications

• Automotive Load Control: Ideal for relay replacements, LED drivers, and motor control in 12V/24V systems.
• Power Distribution: Used in ECUs, body control modules, and battery management systems.
• Industrial Systems: Suitable for solenoid valves, actuators, and high-side switches requiring robust fault handling.
• Open-Load Detection: Critical for diagnostics in safety-critical automotive circuits.

Conclusion of AUIPS6041S

The AUIPS6041S excels in high-reliability automotive and industrial applications, combining low power dissipation, integrated protections, and compact packaging. While obsolete, its fault-tolerant design and automotive-grade durability make it a legacy solution for systems demanding high-side switching with minimal external components. Engineers valuing robustness over availability may still find it suitable for legacy designs or specific repair scenarios.
