Applications

The SP8K22FRATB is a transistor array capable of driving large currents into low-impedance or capacitive loads while offering protection against inductive loads. With such abilities, the array is well suited for high-power supply and energy management applications, such as power factor correction, resonance compensation and LLC resonant converters. It is also suitable for high-speed switching applications, like automotive electrical systems, for fast power MOSFETs.

The SP8K22FRATB is designed for high-performance mobile and wired network applications due to its high-speed switching capabilities and integrated power management features. It is also well suited for use in high-power server and storage applications, as its high power-switching capability makes it ideal for large-scale power supplies.

Functionality

The SP8K22FRATB is a full-bridge array featuring integrated power MOSFETs, BiCMOS logic and power transistors. It offers a wide range of protection functions, including programmable overvoltage protection, overcurrent protection, thermal protection and soft-start functionality. The array also has a high-performance switching capability, allowing it to achieve switching speeds up to 500V per microsecond.

The array also offers a wide range of current-sharing capabilities, allowing controlled and balanced output current regardless of how the outputs are connected. This allows for improved efficiency, reduced system losses and improved system reliability. The SP8K22FRATB also features integrated overvoltage protection and active short-circuit protection, which protect the array and connected external devices from damage.

Working Principle

The operation of the SP8K22FRATB is based on the bi-CMOS logic and power transistors. The array consists of two cascaded MOSFETs connected in a full bridge configuration. The two MOSFETs are referred to as the top MOSFET and the bottom MOSFET. The top MOSFET is connected between the drain and source, while the bottom MOSFET is connected between the gate and source. When a positive voltage is applied to the gate, the top MOSFET is switched on, allowing current to flow through the drain and the source. When the voltage is removed, the top MOSFET is switched off, preventing current from flowing through the drain and the source.

The BiCMOS logic transistors perform the basic logic operations, such as enabling and disabling the power transistors, adjusting the current level and authenticating the current in order to protect against overvoltage, overcurrent, and thermal protection.

The SP8K22FRATB array offers a wide range of features and benefits, making it suitable for a variety of applications. Its ability to drive high currents into capacitive and low-impedance loads, coupled with its integrated protection functions, make it especially well suited for high-power supply and energy management applications. It also features high-speed switching capabilities, making it an ideal choice for automotive, server and storage applications.
