The SI8230BD-D-IS series of Gate Drivers from Isolators are designed to provide high power and high-frequency performance for various applications. They have been designed to provide isolated outputs for multiple output applications. The drivers offer high frequency and low-voltage-clamp operation, as well as a wide operating temperature range. The SI8230BD-D-IS series also offers a wide range of features that make them an ideal choice for many industrial applications.

The SI8230BD-D-IS is a two-level gate driver, meaning that it can conduct two or more outputs at the same time while also providing short-circuit protection. It is also capable of switching high power levels up to 1.5A and 20V. It also features internal protection diodes, a low on resistance of 0.8 ohms, and an adjustable driver voltage of up to 30V.

The SI8230BD-D-IS Gate Drivers are ideal for controlling power supplies and inverters as they have a high switching frequency range of up to 800 kHz, are capable of driving multiple output devices with short-circuit protection, support pulse-frequency-modulated (PFM) and constant power mode, and are suitable for driving low-side switches. They also feature low power consumption of 1.5 Watts (typical) and have a wide operating temperature range of -40 to 85⁰C.

The applications of the SI8230BD-D-IS Gate Drivers include industrial drives, motor control, electronic HVAC, control units, Industrial Control systems, lighting, and switch Mode Power Supplies.

The working principle of the SI8230BD-D-IS Gate Drivers is relatively simple. It consists of two main components, the input voltage and the output voltage. When a voltage is applied to the input, the output voltage is set to the desired level by an internal voltage reference.

Once the desired voltage is set, the input and output voltages are connected in series to form a continuous path of current. As the current passes through the series-connected components, the inductors present in the input voltage cause the output voltage to rise. This results in an increased output voltage, which then produces higher current values and, in turn, higher power levels.

In addition, the SI8230BD-D-IS Gate Drivers have an integrated shutdown circuit that ensures safe shutdown when the voltage exceeds the preset level. This is an important feature, as it prevents damage to the device itself, as well as the devices which are connected to it.

The SI8230BD-D-IS Gate Drivers, with their high power and frequency performance, wide operating temperature range, low-voltage-clamp operation, and adjustable driver voltage, make them an ideal choice for many industrial applications. They provide improved efficiency, improved power level, and higher power levels while still providing the necessary protection from over-voltage conditions.
