An AON6400 is a 2-gate normally off GaN power switch. It is a monolithic integration of two GaN enhancement mode high electron mobility transistors (HEMTs) with a mid-gate protected by a high-bandgap integrated isolation oxide. It is suitable for power management needs in applications such as adapter, streaming media, laptops, tablets, game console and more. Additionally, the AON6400 also supports in-system power management (ISPM), end user power management (EPM), high voltage drive control and low voltage supply for a wide variety of standard and customizable power design solutions.

GaN (Gallium Nitride) is a wide gap semiconductor material that is highly beneficial for use in high frequency switching applications. It is efficient, lightweight, and has superior thermal and mechanical properties compared to its silicon (Si) predecessors. Thus, GaN based power switches are becoming increasingly popular in the power management field.

The AON6400 is equipped by ON Semiconductor, making power management applications easier, more flexible and reliable. It is the industry’s first 2-gate, normally off GaN power switch and has been developed with the highest safety standards. It consists of two GaN enhancement mode HEMTs with a mid-gate protected by a high-bandgap integrated insulation oxide (IOX) providing superior power efficiency.

The most important function of the AON6400 is that it provides an in-system power management (ISPM) and end user power management (EPM) capability. An ISPM allows the power switch to take a direct, temperature-controlled and other environmental inputs from the application, which makes it responsive and able to automatically manage the power switch in the event of an overload, overvoltage, and other conditions. An EPM feature on the other hand, allows for remote operation of the power switch and allows for different power levels on multiple power domains.

The AON6400 also has high and low voltage inputs, allowing it to be used in both high and low power applications, or as a bridge between components that operate at different voltages. Additionally, the AON6400 has a wide voltage range and can handle up to 200 volts, allowing it to be used in a variety of applications, including high-power applications, such as motor drivers and power supplies.

The AON6400’s main features are its superior power efficiency and low switching losses. The switch’s integrated IOX layer ensures low power loss and offers superior on-resistance compared to standard MOSFET technologies. It has also been designed to reduce EMI (electromagnetic interference) compared to off-the-shelf products. This makes the AON6400 ideal for applications where low noise and fast switching is required.

Apart from power management applications, the AON6400 is suitable for applications such as high-speed digital regulators, automotive systems, power systems, industrial power supplies and more. The device is also compliant with RoHS (Restriction of Hazardous Substances) Directive 2002/95/EC and has passed a range of safety tests, making it suitable for a number of stringent application requirements.

In conclusion, the AON6400 is an advanced power switch ideal for power management applications. It has superior power efficiency, low noise and fast switching, making it suitable for a variety of applications. Furthermore, it is compliant with RoHS and has passed a range of safety tests, making it suitable for many industrial and home applications.
