The SI8281BD-IS is an Isolator – Gate Driver designed for use in industrial applications. It is capable of providing a high level of isolation between the controlling device and the driven device while providing optimum performance in a small package. This product is an excellent choice for applications such as switching power supplies, motor drives and industrial automation.The SI8281BD-IS provides a galvanic isolation barrier between the controlling device and the driven device. It is capable of providing up to 2000V of common-mode transient immunity, which helps to prevent interference between the two devices. This allows the user to reliably control and monitor the driven device from a distance. Additionally, the SI8281BD-IS can handle up to 32 isolated I/O pairs and can withstand up to a 256mA sinking and sourcing load.In order to make the product user-friendly, the SI8281BD-IS comes with several built-in features. First, it includes a programmable signal rate for synchronizing with other devices. Secondly, it has a selectable diagnosis mode, which allows the user to set the diagnostic thresholds and respond to detected faults. Additionally, the product includes a root fault detect pin which indicates when a fault has occurred on any of the I/O pairs.The SI8281BD-IS also supports a variety of different gate drivers, allowing it to manage a wide variety of motor types. It is compatible with various IGBT, BJT, relay or mosfet gate driver circuits, as well as with digital load modules. The product is also backed by an Advanced Park Inhibit and Fault Protection feature, as well as a comprehensive error reporting system.Finally, the SI8281BD-IS also brings a wide range of convenience and safety features. This includes a "bus power input detect" function, which senses when the bus voltage is insufficient and switches to standby mode in order to prevent damage to the equipment. Additionally, the product has an over-temperature detection function, which will shut down the system if a high temperature is detected.Overall, the SI8281BD-IS is an excellent choice for industrial applications requiring high levels of isolation and control. Through its galvanic isolation, wide range of built in features, and strong suit of safety functions, the product is an excellent choice for any environment.
