Application Fields

The AUXHA1021RTRL module is designed to provide an efficient and reliable solution to the power distribution and load driving needs of numerous different applications across a wide range of industries and markets, including:• Industrial, automotive and rail applications• Telecommunications and networking• Battery management systems• Medical equipment and laboratory instruments• Aerospace and defense• Gaming and entertainment• Home automation and control systems

Working Principle

The AUXHA1021RTRL module is a highly integrated, space-saving solution, providing a full range of system power control, switching, and load drive functions, from one module. It is based on a rectifier, an integrated circuit (IC), and a load driver, all contained within a single package.The rectifier is a single diode bridge across the input, providing isolated voltage rails and allowing reverse-polarity protection to the IC and load driver. Two capacitors are provided for filtering and noise suppression, and a resistor provides short-circuit protection.The integrated circuit is a digital logic block with a PWM converter, which is connected to the input and provides the control logic signals required to drive the load drive outputs. It also contains logic circuitry to allow the switching between two different output voltages.The load driver circuit is a metal-oxide-semiconductor FET (MOSFET) which is connected to the output of the integrated circuit, and is responsible for driving the load. It uses a metal-oxide-semiconductor field-effect transistor (MOSFET) to provide high frequency switching between the two different output voltages.

Conclusion

The AUXHA1021RTRL is an advanced, integrated power distribution and load driving solution, which provides a cost-effective and efficient power system control. The module incorporates a single-phase Schottky barrier rectifier, an integrated circuit, a load driver, and intelligent control logic into a single, space-saving package. It is suitable for a variety of applications, including industrial, automotive and rail applications, telecommunications and networking, battery management systems, medical equipment and laboratory instruments, aerospace and defense, gaming and entertainment, and home automation and control systems.
