Isolators - Gate Drivers are used to drive the gate of a thyristor or other high current power switch. PS9305L-E3-AX is one isolated gate driver which is specifically designed to drive the gate of N-channel or P-channel MOSFET/IGBTs in online switching power supplies. It can provide high performance gate drive for a wide range of low power and low voltage up to 600V.

The PS9305L-E3-AX application field includes industrial control, motor drive, home appliance, UPS uninterruptible power supply, LED lighting and multimedia communication. It is a fully isolated Gate Driver with isolated supply voltage up to 28V and it offers various features including overvoltage protection, short-circuit protection, active discharge function, and ultra-low dead time control functions. Furthermore, the fast maximum fall time of 10ns and 1.2A peak gate source current allows for reduced switching loss and minimized EMI noise.

The working principle of the PS9305L-E3-AX is based on a simple but effective circuit structure consisting of a high voltage isolated DC to DC converter three-terminal fast opto-couplers and driver circuits. When an input signal is applied to the gate driver, it will drive the power MOSFET/IGBT with a high gate-source current to be switched on or off. The integrated load resistor levels the gate-source voltage to the logic high level when the gate drive circuit is off, ensuring high reliability of the circuit.

The PS9305L-E3-AX features high isolation voltage of 3000V and low propagation delay time with fast rise and fall time. The wide supply voltage range of 4.5V to 28V also helps to ensure stable operation of the driver over a wide range of input voltages. Combined with the integrated overvoltage protection circuit, the drivability of the power MOSFET/IGBT is greatly improved without having to worry about overstressing the output circuits.

Overall, the PS9305L-E3-AX is a high performance isolated Gate Driver capable of driving a wide range of low power and low voltage MOSFET/IGBTs for use in industrial control, motor drive, home appliance, UPS uninterruptible power supply, LED lighting and multimedia communication applications. With its advanced features, high isolation voltage, low propagation delay time, and fast rise and fall times, it is ideal for a variety of switching circuits.
