The AUIPS6121R is a power management integrated circuit (PMIC), specifically designed to facilitate the distribution, switching and isolation of power sources. It is a product of the semiconductor industry leader, ON Semiconductor. The AUIPS6121R’s features and functions make it ideal for applications in a variety of industries including automotive, industrial, medical, and aerospace/defense. This application brief provides an overview of PMICs, the AUIPS6121R, and their associated applications.

PMICs are integrated circuits (ICs) that integrate multiple power supply and management functions onto a single chip. This can enable more efficient power management for various systems. PMICs typically incorporate functions such as voltage regulation, voltage monitoring, thermal protection, DC/DC conversion, and digital power controls. PMICs offer design engineers a powerful and flexible solution for designing robust, reliable and energy efficient systems. The AUIPS6121R is a member of ON Semiconductor’s family of automotive PMICs and is specifically designed to provide robust power management solutions to automotive applications.

The AUIPS6121R is a Power Management Integrated Circuit (PMIC) and is categorized as a Power Distribution Switch, Load Driver, and Load Switch-Load Drive. It is a high-side Current Limiting Load Driver/Switch (CLD/CLS) device. It is capable of sourcing 3A peak current to the load and its integrated charge pump enables the drive signal to be negative on its positive load terminal providing the load with power in either direction. The AUIPS6121R also incorporates an integrated dual-bootstrap charge pump that enables the control signals to be referenced to the high-side power supply.

The AUIPS6121R is designed to offer a robust alternative to solutions that are typically achieved through the use of many discrete components. It integrates seven MOSFETs and a charge pump, as well as a bi-directional current limitation circuit, into a single package, saving designers both space and cost. It provides robust protection to the system against faults that can be caused by ESD, supply shorts, and load transients. The AUIPS6121R also integrates overvoltage (OV) and undervoltage (UV) protection circuits.

The AUIPS6121R’s features and functions make it ideal for use in automotive, industrial, medical, and aerospace/defense applications. It can be used to control battery management systems, HVAC systems, motor management systems, and many other applications that require precise control of a load. It is also well suited for applications that require high-side current limited load drive or load switch-load drive. The integrated charge pump and bi-directional current limitation make the AUIPS6121R well-suited for AC/DC systems, such as use for bridge rectifiers, buck-boost converters, PFCs, and battery chargers.

The AUIPS6121R is a powerful, high-performance PMIC that is designed to provide robust power management solutions to a wide range of applications.
