SI8282CD-IS

The SI8282CD-IS is an optically isolated gate driver, and is designed to drive IGBTs, MOSFETs, and other power semiconductor modules. It offers superior electrical isolation, transient protection, and high reliability. As an isolator, the SI8282CD-IS acts as a power transistor switch to channel electrical energy from a power source to an external device. This isolator is ideally suited for applications where it is necessary to provide heavy load switching, such as DC-DC converters and UPS protection, or where electrical isolation is required due to safety regulations. It is also suitable for automotive power applications and other power conversion applications.

The SI8282CD-IS includes an optically isolated driver and logic control circuits. The optically isolated driver provides electrical insulation properties with an insulation barrier of 20 kilovolts, and a break down voltage of 500 volts. It also has a wide voltage range, up to 24V, and is protected against unexpected over voltage and short-circuit conditions, making it highly reliable. The logic control circuits provide high speed switching, up to 1 MHz, and gate turn-on/turn-off voltage control, for reliable operation. The SI8282CD-IS is also fully RoHS compliant.

The working principle of the SI8282CD-IS is very simple, yet highly effective. It uses an optically isolated driver to transfer the logic signals from the controlling circuitry to the external device, which is the power transistor switch. When the control signals are applied, the power transistor switch is activated, which then controls the flow of energy from the power source to the external device. The optically isolated driver allows the logic switch to be isolated from the power supply, thus preventing shocks and other potential risks.

The SI8282CD-IS is a versatile and reliable isolator that can be used in a variety of applications. It is suitable for use in industrial automation, motor control, renewable energy, and automotive applications where electrical isolation is required. Its ability to provide transient protection and high reliability, coupled with its RoHS compliant design, make it an ideal choice for protecting electronic circuits from unexpected overvoltage and short-circuit conditions. The SI8282CD-IS is the perfect solution for applications that require electrical isolation and reliable power switching.
