Isolators - Gate Drivers are capable of providing safe and reliable isolation between high voltage circuits. The PS9306L2-AX is one such device, a highly efficient gate driver IC which can provide up to 500 V isolation. It is an active-low (bus-driven) isolation device with a built-in timer for continuous over-voltage protection.

The PS9306L2-AX is an integrated circuit designed to drive the gate of a power MOSFET, IGBT, or SCR in pulse width modulated applications. It is specifically designed to provide galvanic isolation between the control circuitry and the gate driver itself. This device is also capable of providing both standard and multiply inputs, as well as precise voltage and current regulation. In addition, 4.5V to 18V input voltage and a wide variety of frequencies (250kHz to 2MHz) are supported.

The PS9306L2-AX has two main application fields, namely driving the gate of a power MOSFET, IGBT, or SCR, and providing galvanic isolation. As a gate driver, the device is capable of driving gates up to 10A and providing very high switching speed. With good voltage and current regulation, it is ideal for driving the gates of power FETs in pulse width modulation applications. In addition, its high efficiency ensures low power losses and high performance.

As a galvanic isolation device, the PS9306L2-AX is capable of providing up to 500 V isolation between high voltage circuits. The device has speed-compensated over-voltage protection (OVP) for added safety. It is also designed to be compliant with most widely used safety standards, including IEC/UL 60950-1. Furthermore, the device has a built-in timer which can be used to identify transient voltage conditions and prevent dangerous over-voltage.

In terms of working principle, the PS9306L2-AX is based on the coupling of a high-voltage transformer, typically CMOS-based tracks, and a latch circuit. The transformer is coupled with the drive voltage to switch the output of the device. The device is also designed with a short delay feature to ensure a faster turn-on of the system. The latch circuit provides precise voltage or current regulation, depending on the input voltage.

The PS9306L2-AX is an efficient and robust gate driver that provides reliable isolation between high voltage circuits. When designed and utilized properly, it can provide robust performance with very low power losses. In addition, the speed-compensated OVP feature ensures safe operation in all conditions. The device is ideal for driving the gate of power MOSFETs, IGBTs, and SCRs in pulse width modulated applications.
