Signal Isolated RS-485 Transceiver With Integrated DC to DC Converter

Part Number: NSiP83086
Brand: Novosense

Description

The NSiP83086 series are high-reliability isolated full-duplex RS-485 transceivers with an integrated DC-to-DC converter. These devices are designed for various applications that require robust and isolated communication. Here’s an overview of their key features and applications:

Key Features:

  1. Insulation Voltage: The NSiP83086 series provides up to 5000Vrms of insulation voltage, ensuring strong electrical isolation between the RS-485 bus and other parts of the system.
  2. Integrated Isolated DC-to-DC Converter: These devices feature an integrated isolated DC-to-DC converter that uses an on-chip transformer. The feedback PWM (Pulse Width Modulation) signal is sent to the primary side (Isolator Side1) by a digital isolator based on Novosense capacity isolation technology.
  3. I/O Voltage Range: The devices support an I/O voltage range of 1.8V to 5.5V for MCU (Microcontroller) connections, making them compatible with a wide range of microcontrollers.
  4. Power Supply Voltage: Depending on the specific model (NSiP83086, NSiP83086C, NSiP83086V), the power supply voltage varies. For example, VDD ranges from 4.5V to 5.5V for NSiP83086, and VDDL ranges from 1.8V to 5.5V.
  5. Overcurrent and Overtemperature Protection: The devices are equipped with overcurrent and overtemperature protection mechanisms to safeguard their operation.
  6. High Common-Mode Transient Immunity (CMTI): These transceivers offer a high CMTI of ±150kV/us, ensuring they can handle fast voltage transients on the RS-485 bus.
  7. Data Rate: The data rate supported by the NSiP83086 series is 16Mbps, making them suitable for high-speed RS-485 communication applications.
  8. Up to 256 Transceivers on the Bus: With a 96kΩ input impedance, these devices allow for the connection of up to 256 transceivers on the RS-485 bus, which is ideal for large network configurations.
  9. High System-Level EMC Performance: The BUS pins meet IEC61000-4-2 ±8kV ESD requirements, and other pins meet IEC61000-4-2 ±7kV ESD requirements, ensuring high-level EMC performance.
  10. Operating Temperature Range: They can operate within a wide temperature range, from -40℃ to 105℃, suitable for various environmental conditions.
  11. RoHS-Compliant Packages: The NSiP83086 devices are available in RoHS-compliant packages, including SOW20 and SOW16.

Safety Regulatory Approvals:

These devices have undergone safety certification and regulatory approvals, including UL recognition, CQC certification, CSA component notice 5A, and DIN VDE V 0884-11:2017-01.

Applications:

The NSiP83086 series is suitable for a range of applications, including:

  • Industrial automation systems.
  • Isolated RS-485 communication in industrial environments.
  • Smart electric meters and water meters.
  • Security and protection monitoring systems.

These devices are designed to provide reliable and isolated communication in challenging and noisy environments, making them well-suited for industrial and utility applications where robust and safe data transfer is essential.
