Ultra Small Package Dual-Channel Digital Isolators

Part Number: NSi8120D0
Brand: Novosense


NSi8120D0 devices are dual-channel digital isolators designed for high reliability and electromagnetic compatibility. They offer insulation, high-speed data transmission, low power consumption, and are versatile for a range of applications requiring isolated communication and protection against electrical disturbances.

  1. Insulation and Immunity: The NSi8120D0 devices are designed to offer high reliability and come in a compact package. They can withstand an insulation voltage of up to 2,000VRMS, making them suitable for applications where electrical isolation is critical. These devices also provide high electromagnetic immunity and emit low electromagnetic interference (EMI) while consuming low power.
  2. Data Rate and CMTI: The NSi8120D0 supports data rates of up to 150Mbps, making them capable of handling relatively high-speed digital communication. They also possess a high Common-Mode Transient Immunity (CMTI) of up to 200kV/us, indicating their ability to tolerate rapid changes in common-mode voltages.
  3. Wide Supply Voltage Range: These devices are designed to work with a wide supply voltage range, from 2.5V to 5.5V. This feature allows them to be easily interfaced with various digital systems that operate within this voltage range.
  4. EMC Performance: The NSi8120D0 devices provide high system-level EMC (Electromagnetic Compatibility) performance, enhancing the reliability and stability of their usage. They offer enhanced immunity against electrostatic discharge (ESD), electrical fast transient (EFT), and surge events.
  5. Output Level Configuration: The devices offer the option to set the default output level as either high or low when the input power is lost. This flexibility can be useful in various applications.
  6. Low Power Consumption and Propagation Delay: These devices have low power consumption, drawing only 1mA per channel at a data rate of 1Mbps. They also feature a low propagation delay of less than 10ns, ensuring quick signal transmission.
  7. Applications: The NSi8120D0 devices are suitable for various applications, including industrial automation systems, isolated communication interfaces such as SPI, RS232, and RS485, general-purpose multichannel isolation, and motor control systems. Their electrical isolation capabilities make them valuable in scenarios where isolating sensitive components from noise or high-voltage systems is required.
