The MAX14934–MAX14936 are a family of four-channel, 5kVRMS digital isolators utilizing Maxim’s proprietary process technology. For applications requiring 2.75kVRMS of isolation, see the MAX14930–MAX14932. The MAX14934–MAX14936 family transfers digital signals between circuits with different power domains at ambient temperatures up to +125°C.

The MAX14934–MAX14936 family offers all three possible unidirectional channel configurations to accommodate any four-channel design, including SPI, RS-232, RS-485, and large digital IO modules. For applications requiring bidirectional channels, such as I²C, refer to the MAX14937.

Devices are available with data rates from DC up to 1Mbps, 25Mbps, or 150Mbps. Each device is also available in either a default high or default low configuration. The default is the state an output goes to when its input is unpowered. See the Product Selector Guide and Ordering Information for the suffixes associated with each option. Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators.

The MAX14934–MAX14936 are available in a 16-pin wide body (10.3mm x 7.5mm) SOIC package. All devices are rated for operation at ambient temperatures of -40°C to +125°C.

Applications

  • Battery Management
  • Fieldbus Communications for Industrial Automation
  • General Multichannel Isolation Applications
  • Isolated SPI, RS-232, RS-485/RS-422
  • Medical Systems

Features and Benefits

  • Ease of Use
    • Easy Powering Through Micro-USB or Test Points
    • SMA Connectors to Connect to External Equipment
  • Guaranteed Up to 5kVRMS Isolation (for the Wide-Body SOIC Version)
    • Also Evaluates the 2.75KVRMS Versions.

Product Details

The MAX1493X evaluation kit (EV kit) demonstrates the functionality of the MAX1493X 4-channel, unidirectional, digital isolators in a 16-pin, SOIC surface-mount package. The functionality and performance of the QSOP versions (MAX1413x) can be tested indirectly by using this EVkit populated with any of the equivalent narrow or wide SOIC (MAX1493x) devices. The functionality and electrical performance of the QSOP versions are identical to their corresponding SOIC versions. The EV kit features two independent isolated power supplies independently adjustable to +5V.

Applications

  • Battery Management
  • Fieldbus Communications for Industrial Automation
  • General Multichannel Isolation Applications
  • Isolated SPI, RS-232, RS-485/RS-422
  • Medical Systems
