AUIPS7221R dual-channel digital isolator

The AUIPS7221R is a dual-channel intelligent power switch and digital isolator designed by Infineon Technologies. It integrates two high-side MOSFET drivers with advanced protection and diagnostic features, providing safe, reliable, and efficient power switching for industrial, automotive, and embedded control applications.

Operating as a smart high-side switch, the AUIPS7221R offers galvanic isolation between logic control and load circuits, protecting sensitive microcontrollers from high-voltage transients. Each channel can drive loads independently with built-in overcurrent, overtemperature, and short-circuit protection, ensuring robust and fail-safe operation.

With its CMOS-compatible digital inputs, low R_DS(on), and fast switching speed, the AUIPS7221R is ideal for relay replacement, actuator control, motor driving, and industrial automation systems.
