The SI8271DB-IS is a highly efficient isolation-based gate driver available in the market, designed for the use in high power applications. It isolates up to 200V of load from the power source and provides an output voltage/current range up to 6.5V/2A. The device is ideal for applications such as automotive, industrial motor drives, solar inverters and other industrial applications.

The SI8271DB-IS gate driver integrates two isolated high side and low side outputs, respectively for a half-bridge low-side and a half-bridge high-side driver. It also provides two galvanic-isolated inputs (IN and EN) to solve delays in gate drive control, so the device can execute high-side and low-side output within a short period of time.

Applications that require isolation-based circuits can benefit greatly from the usage of this product. This product does not only provide efficient isolation, but also reduce the switching losses caused by capacitive and inductive loads. Moreover, its robust stainless steel casing provides superior protection from the external environment, making it an ideal choice for hazardous working conditions.

The working principle of the SI8271DB-IS is based on the principle of magnetic resonance. A primary winding is attached to both thermo-isolated inputs (IN and EN) and excites the resonance circuit. The two secondary windings will be excited too, providing either 5 or 12V DC output. Eventually, both the low-side and high-side outputs are galvanically isolated due to their recovery diodes.

The SI8271DB-IS can be used for the control of both AC and DC motors. It provides good protection against overload and can detect over-temperature and over-current conditions. This intelligent device comes with a user-friendly interface, allowing an easy configuration of output parameters.

The SI8271DB-IS can also be used in the field of smart metering systems. Its insulation provides the necessary security and isolation needed in this application. Additionally, its high current driving capability and precise output voltage control allows for an accurate and reliable measurement of current and voltage in smart metering systems.

In conclusion, the SI8271DB-IS is an effective, reliable and efficient gate driver, perfect for applications such as power supplies, DC and AC motor drives, smart metering systems and hazardous working environments. Its integration of efficient insulation, robust operating conditions and complete overwrite protection make this device an ideal choice for your isolation-based applications.
