AUIPS1051LTR

AUIPS1051LTR Description

The AUIPS1051LTR from Infineon Technologies is a low-side power switch designed for automotive-grade applications, integrating a single N-channel MOSFET with a 1:1 input-to-output ratio. This surface-mount (SOT-223) device operates within a 6V to 28V load voltage range and delivers a maximum output current of 1.3A, making it suitable for moderate-power switching tasks. Although marked as obsolete, it remains relevant for legacy designs due to its robust fault protection (fixed current limiting and over-temperature shutdown) and low Rds(On) of 160mΩ, ensuring efficient power handling. The REACH-unaffected and MSL 2 (1 Year) ratings ensure compliance with environmental and handling standards.

AUIPS1051LTR Features

• Automotive-Grade Reliability: Meets stringent automotive requirements for durability and performance.
• Integrated Protection: Built-in current limiting and thermal shutdown enhance system safety.
• Low On-Resistance: 160mΩ Rds(On) minimizes power losses, improving efficiency.
• Wide Load Voltage Range: Supports 6V to 28V, ideal for 12V/24V automotive systems.
• Compact SOT-223 Package: Space-saving surface-mount design for PCB integration.
• No External VCC Required: Simplifies design by eliminating the need for a separate supply.

AUIPS1051LTR Applications

• Automotive Load Control: Ideal for relay replacements, lighting modules, and motor drivers in vehicles.
• Industrial Switching: Used in low-voltage power distribution for sensors and actuators.
• Consumer Electronics: Suitable for battery-powered devices requiring efficient load management.
• Legacy System Maintenance: Supports obsolete designs needing reliable, fault-protected switching.

Conclusion of AUIPS1051LTR

The AUIPS1051LTR excels in automotive and industrial applications where compact size, low power dissipation, and integrated protection are critical. While obsolete, its high reliability, wide voltage range, and efficient switching make it a pragmatic choice for legacy or cost-sensitive designs. Engineers should consider alternative Infineon solutions for new projects but may leverage this device for existing systems requiring proven performance.
