Description
The Infineon AUIPS8121R is an automotive-grade protected high-side intelligent power switch for controlling 12 V automotive loads. It is supplied in a DPAK-5 surface-mount package. This device integrates a power MOSFET, a charge pump, and protection features.
The AUIPS8121R is engineered for high-side switching. It provides low on-resistance to minimize power loss. Built-in protection includes overtemperature, short circuit, overcurrent, and undervoltage conditions. It features diagnostic feedback for fault detection and system monitoring.
Typical applications include automotive lighting systems such as headlights, fog lights, and brake lights. It is used for solenoid and valve control in engine and transmission systems. This part serves as a relay and fuse replacement in smart power distribution units. It drives resistive, inductive, or capacitive loads in 12 V or 24 V systems. It is also for industrial or transportation applications requiring protected high-side load control.
The AUIPS8121R is part of the Infineon IPS family. It supports operation in harsh environments and simplifies PCB layout compared to discrete MOSFET and driver combinations.
Part number AUIPS8121R or AUIPS8121RTRL. Manufacturer Infineon Technologies.
