Digital Isolators

Digital isolators provide galvanic isolation between a host system and a device such as a sensor or actuator. They enable isolated communication and help to protect the host system from faults and high voltage. Digital isolators also reduce noise and minimize the impact of common-mode signals on both sides of the isolation boundary. SI8463BA-A-IS1 is an digital isolator product from Silicon Labs, designed for a wide range of applications and working principles.

SI8463BA-A-IS1 Application Field and Working Principle

The SI8463BA-A-IS1 digital isolator is a single channel, voltage input, I2C compatible transceiver with 1.5KVDC isolation rating. It supports bidirectional level shifting for the I2C bus, with an input voltage range of 2.0V to 5.5V. The SI8463BA-A-IS1 provides a robust and reliable solution for isolating I2C interface of a microcontroller or a system. It is ideal for applications such as industrial motor control and for isolating ground loop problems relating to I2C sensors.

The SI8463BA-A-IS1is supplied with an integrated ADC that can be used to measure the input voltage. The ADC can be accessed via an integrated I2C interface, allowing for easy, low-cost monitoring of the voltage level. The device also incorporates power-on reset and allows the electrical isolation of power and ground lines between both sides of the isolation boundary. It is also suitable for intelligent sensor applications and is fully compatible with the I2C protocol.

The SI8463BA-A-IS1 is based on the proven Silicon Laboratories High-CMR technology. This technology provides a high-speed signal isolator with a 1.5KVDC isolation rating. It utilizes high voltage CMOS processes and silicon-on-insulator (SOI) substrate to achieve ultra-low power operation with excellent EMI performance. It features low propagation delay times of up to 20ns,low jitter of up to 5ns, and high data rate of up to 3.4 Mbps. Furthermore, the SI8463BA-A-IS1 operates with a supply voltage range of 2.7V to 5.5V and offers up to 8 line drivers and 8 line receivers.

In addition, the SI8463BA-A-IS1 is compliant with ISO15408 certification, offering the highest level of security and reliability. The device offers superior signal-to-noise immunity, transient protection, and common-mode isolation. The SI8463BA-A-IS1 is available in eight pin SOIC, SOICW, and Compact TSSOP packages. It is pin and software compatible with other similarly rated single- and dual-port isolators. The device is fully RoHS compliant with reduced hazardous substances.

In summary, the SI8463BA-A-IS1 digital isolator from Silicon Labs is a robust, reliable, and economical solution for industrial motor control applications and intelligent sensor systems. With its high-speed, 1.5KVDC isolation rating, low power operation, and certified data-rate, the SI8463BA-A-IS1 provides the reliability and performance required for critical, safety, and isolation applications.
