The MAX14930–MAX14932 are a family of 4-channel 2.75kVRMS digital isolators utilizing Maxim’s proprietary process technology. The MAX14130–MAX14131 are 4-channel 1kVRMS digital isolators in smaller footprint QSOP packages. For applications requiring 5kVRMS of isolation, see the MAX14934–MAX14936. The MAX14930–MAX14932 family transfers digital signals between circuits with different power domains at ambient temperatures up to +125°C.

The MAX14930–MAX14932 family offers all three possible unidirectional channel configurations to accommodate any 4-channel design; including SPI, RS-232, RS-485, and digital I/O applications. For applications requiring bidirectional channels, such as I2C, see the MAX14933.

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 MAX14930–MAX14932 are available in both a 16-pin wide body (10.3mm x 7.5mm) and narrow body (9.9mm x 3.9mm) SOIC package. The MAX14130–MAX14131 are available in a 16-pin (6mm x 5mm) QSOP 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

Evaluation Kit for the MAX14130/MAX14131/MAX14930/MAX14931/MAX14932/MAX14934/MAX14935 and MAX14936

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 Detail

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.
