Isolators - Gate Drivers

HCPL-3120-360E application field and working principle

HCPL-3120-360E is a high current optocoupler featuring 4 isolated output channels and is commonly used as a gate driver in isolating different parts of the circuit from each other. This optocoupler is mainly designed to transfer pulse signals and control the current of transformer and inductors by isolating their surroundings and its application fields also range from protecting the controllers input in a solar inverter, an electric motor to isolating logic elements from power elements in automotive and industrial applications.Intermeshing the working of the optocoupler, the HCPL-3120-360E is an integrated device that includes an optical transmitter incorporating a LED and four phototransistors that act as the receiver. The center of the isolator is a gas-filled tube dielectric which acts as the insulator. The transmitter and the receiver both have two separate connections between each other. The transmitter gets the signal from the input terminal while the receiver out output to the intended device.As mentioned earlier, the HCPL-3120-360E can be used in a variety of applications as it offers a safe isolation to the respective elements. Thanks to the gas-filled tube insulator, the high current supply needed to control and manage the components connected to it is isolated from the low voltage used for the other parts of the circuit. Furthermore, the high insulation voltage helps to protect the components connected after it from voltage surges, spikes, and other environmental factors.The HCPL-3120-360E optocoupler is also low on dissipation with a minimum on-state voltage of 36V and a maximum on-state current of 360mA. Additionally, it also has a moderate response time ranging from 20 to 80ns depending on the current applied.To sum it up, the HCPL-3120-360E optocoupler is the perfect choice for isolating different parts of the circuit from each other as it can provide a safe environment of operating to the components. Its long-term reliability, safety, and low power dissipation make it the perfect choice for high current applications.
