Isolators - Gate Drivers

The VO3120 is an isolated gate driver module designed for MOSFET applications. It features opto-isolation between the input and output stage, giving it high isolation capability compared to other gate driver components. This isolator is designed to drive high power, low power, and high impedance MOSFETs with high efficiency E-MOS or MOSFET transistors. The output stage is capable of driving both P and N channel MOSFETs and has a maximum peak drive capability of 10V. The integrated zero-crossing technology allows for fast and efficient switching.

The VO3120 module has five electrical input/outputs which include: an input signal, an enable signal, a P control signal, an N control signal, and a signal ground. The input signal and enable signals are used together to activate the device. The P and N control signals are used to drive the MOSFETs. The signal ground references the electrical isolation capability of the VO3120.

The VO3120 isolator has a wide range of applications, and has been used in automotive, HVAC, solar, and DC-DC converter systems to drive power MOSFETs. Its flexibility makes the VO3120 ideal for use in applications such as high efficiency power conversion, high power switching, and gate driver isolation. The device can be utilized in any system requiring E-MOS switching of power transistors.

The VO3120 gate driver module works by using integrated zero-crossing technology, which allows for fast and efficient switching. The input and enable signals are used together to activate the device, while the P and N control signals are used to drive the MOSFETs. When the input signal is a high level, the enable signal will turn on the output stage and open the P and N control channels. The P and N control signals will pull the base and gate of the MOSFETs up and down, respectively. When the input signal returns to a low level, the enable signal will turn off the output stage, and the P and N control signals will be turned off. This will ensure that the MOSFETs are switched off.

The VO3120 isolator is a reliable, cost-effective solution for high-power or high-impedance applications requiring E-MOS switching of power transistors. Its high output coaxial format allows for easy integration into existing systems, while its integrated zero-crossing technology ensures fast and efficient switching. The integrated electric isolation capability of the VO3120 also makes it an ideal choice for applications which require high isolation, such as automotive, HVAC, and solar systems.
