PS9306L-AX Application Field and Working Principle

PS9306L-AX isolated gate drivers are one of the series of optical isolators from Power-Sonic Corporation. These gate drivers are designed with excellent electro-optical isolation features. PS9306L-AX gate drivers are mainly used in programmable logic controllers (PLCs), switches, power supplies, solenoid valves, contactors and drives.

Essentially, PS9306L-AX isolators work by using an optical isolation feature that separates the input and output circuits so as to avoid interference caused by electrical component failure, electromagnetic interference or ground loops. In addition, these isolators provide superior galvanic isolation capabilities that prevent collateral damage from a failing electrical component. Galvanic isolation also helps isolate the driving circuit from the power supply, providing optimal electric shock protection in applications where an unexpected shock may occur. This is especially important in applications where hazardous voltage levels are present.

The working principle of a PS9306L-AX isolated gate driver is based on the principle of utilizing optical transmission between the input and output. Specifically, the input side has a light source, such as an LED, and the output side has a photodiode. The LED generates light which is guided through an optoelectronic isolator, modulated by an electric signal, onto the photodiode. The photodiode will then convert the modulated light into electrical signals which are then sent to the output device. This way, the electrical signals are isolated from the input and output devices, allowing for communication across different devices without interference.

In addition, the gate drivers can enable Fieldbus, Profibus, CANbus, DeviceNet, Ethernet and CANopen communications. This way, it can enable distributed control, monitor close loop operations in systems, provide optical link redundancy and meet the industrial automation protocols. Moreover, Ps9306L-AX gate drivers also provide user programmable features such as Pulse Rate Modulation (PRM), Frequency Modulated (FEM) and Standby (STB) mode.

Overall, PS9306L-AX gate drivers are ideal for a variety of applications, such as automotive, industrial automation and security. These isolators provide excellent and advanced electro-optical data transmission and galvanic isolation to minimize cross-talk and reduce system failures. Furthermore, these isolated drivers can help to reduce electrical noise, interference, ground loops and enable fast response times for optimal performance.
