AUIPS7145R

AUIPS7145R Description

The AUIPS7145R from Infineon Technologies is a high-side power switch designed for automotive-grade applications, offering robust performance in demanding environments. This N-channel MOSFET-based load driver integrates a 1:1 input-to-output ratio and operates within a 6V to 60V load voltage range, making it suitable for a variety of 12V/24V automotive systems. With a 2.1A maximum output current and a low 75mΩ typical Rds(on), it ensures efficient power delivery with minimal conduction losses. The device features current limiting (fixed) and over-temperature protection, enhancing system reliability. Although marked as obsolete, its design remains relevant for legacy systems requiring high-side switching solutions.

AUIPS7145R Features

• High-Side Configuration: Simplifies wiring by eliminating the need for a separate supply voltage (Vcc/Vdd not required).
• Automotive-Grade Compliance: Meets stringent automotive reliability standards.
• Low On-Resistance: 75mΩ Rds(on) reduces power dissipation and improves efficiency.
• Integrated Protections: Fixed current limiting and thermal shutdown safeguard against faults.
• Surface-Mount DPAK Package: Compact and suitable for space-constrained PCB designs.
• Wide Operating Voltage: Supports 6V–60V loads, ideal for 12V/24V battery systems.

AUIPS7145R Applications

• Automotive Load Control: Powers relays, solenoids, and lighting systems in vehicles.
• Industrial Switching: Suitable for actuators and motor drivers in harsh environments.
• Power Distribution Modules: Used in fuse boxes and electronic control units (ECUs).
• Legacy System Maintenance: Ideal for servicing older designs requiring high-side drivers.

Conclusion of AUIPS7145R

The AUIPS7145R excels in high-side switching applications, combining low conduction losses, robust protection, and automotive-grade durability. While obsolete, its performance remains competitive for legacy automotive and industrial systems. Engineers seeking a reliable, high-voltage switch with integrated safeguards will find this device a proven solution. For newer designs, Infineon’s updated portfolio may offer enhanced alternatives.
