The PS9308L-E3-AX is a high performance, monolithic/bipolar digital isolator integrated circuit (IC) optimized for sampling and isolation in high speed switched signal applications. This device is designed to eliminate the electrical noise that is caused by electrical disturbances from high speed, short-range transmission of signals. It is part of the Isolators - Gate Drivers class of digital isolators, which offer gate drive solutions to simplify the design and implementation of switching power supplies, providing increased performance and reduced noise compared to traditional isolators.

The PS9308L-E3-AX is optimized to provide more than 3528Vrms of isolation and a typical propagation time of 1.8ns. It has a ripple voltage tolerance of 100mV for an input voltage range of 3V to 6V and an output voltage range of 0V to 5V. In addition, the device offers a 400Mbps data rate, supporting a variety of digital isolation protocols, such as I²C, SPI, CANbus, etc. It also features short circuit protection, reducing the risk of over-voltage spikes.

This digital isolator has two halves, a transmitter half and a receiver half. The transmitter half is connected to the input signal source and has a control circuit that receives the input signal and encodes it into a digital signal, using Pulse Width Modulation (PWM) or Return to Zero (RZ) modulation techniques. The output of the transmitter is then transmitted over an optical fiber to the receiver half, which contains a photodiode to convert the optical signal into an electrical signal and a control circuit to decode the encoded PWM or RZ signal.

The PS9308L-E3-AX is a highly reliable digital isolator, providing a safe isolation barrier between systems. It is also designed to meet ESD, EMI, and EOS/EMI requirements, providing enhanced immunity for sensitive equipment. Additionally, it is RoHS compliant, allowing for extensive applications in a variety of fields, such as industrial control systems, motor control systems, power conversion systems, and instrument control systems.

In summary, the PS9308L-E3-AX is a high-performance digital isolator optimized for short-range transmission of signals, featuring 3528Vrms of isolation, a typical propagation time of 1.8ns, a 400 Mbps data rate, and short circuit protection. This device is part of the Isolators - Gate Drivers class of isolators and provides enhanced immunity for sensitive equipment, making it suitable for a variety of applications.
