Digital isolators provide the electrical isolation necessary to maintain system safety and performance and are often used in high-voltage applications such as motors, power systems, and hazardous areas. The SI88641EC-IS, from Silicon Laboratories, is a family of galvanically isolated safety digital isolators that offer 6 kV of isolation for a wide variety of industrial and consumer applications.

The SI88641EC-IS features a slim, low-profile “STQFN” package. This package optimizes the product’s size and weight for applications that require high isolation levels and don’t have sufficient space in the board layout. The device also includes an integrated signal transformer and protection circuits to provide robust transient protection. This helps the device handle high transient voltages such as those encountered in motor drives or power conversion systems.

The SI88641EC-IS also has a low propagation delay of less than 10 ns. This allows for a high data rate and makes it suitable for most digital switching applications. The device is optimized for a wide variety of serial protocols, including SPI, I2C, and UART. It also supports both 3.3VDC and 5VDC power supply voltages.

The SI88641EC-IS offers up to 6 kV of isolation between the input and the output side of the device. This is accomplished using Silicon Laboratories\' proprietary planar transformer technology, and provides a reliable isolation barrier for data and power. The device also includes on-chip ESD protection, over-temperature protection, and reverse-voltage protection to ensure reliable performance in high-voltage, high-temperature industrial or consumer applications.

The SI88641EC-IS is available in a 3.3V supply and 5V supply version and is supported by the Silicon Laboratories\' Simplicity Studio, a set of development tools that enable rapid prototyping and workflows. The device is also supported by Silicon Laboratories\' Inter-Integrated Bus (I2C) low-level drivers and can be used with the company\'s reference design for a fast and predictable system response.

The SI88641EC-IS is suitable for a broad range of applications in the industrial, automotive and consumer markets. It offers high electrical isolation in a compact, low-profile package. The device provides robust transient protection and operates over a wide temperature range. And with support from Silicon Laboratories\' tools, the SI88641EC-IS can be used to create reliable and robust industrial and consumer solutions.
