The MAX12934-MAX12935 are fast, low-power, 2-channel digital galvanic isolators using Maxim’s proprietary process technology. These devices transfer digital signals between circuits with different power domains while using as little as 0.65mW per channel at 1Mbps with a 1.8V supply.

The two channels of the MAX12935 transfer data in opposite directions, making the MAX12935 ideal for isolating the TX and RX lines of a transceiver. The two channels of the MAX12934 transfer data in the same direction.

The MAX12934/MAX12935 have an isolation rating of 5kVRMS for 60 seconds. Both devices are available with a maximum data rate of either 25Mbps or 200Mbps and with outputs that are either default-high or default-low. The default is the state the output assumes when the input is not powered or if the input is open-circuit. See the Ordering Information and Product Selector Guide for 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 MAX12934/MAX12935 are available in a 16-pin, wide-body SOIC package. The package material has a minimum comparative tracking index (CTI) of 600V, which gives it a group I rating in creepage tables. All devices are rated for operation at ambient temperatures of -40°C to +125°C.

Applications

  • Battery Management
  • Fieldbus Communications for Industrial Automation
  • General Isolation Application
  • Isolated RS232, RS-485/RS-422, CAN
  • Medical Systems

MAX1293XWEVKIT

Evaluation Kit for the MAX12934/MAX12935

Evaluation Kit for the MAX12934/MAX12935

Features and Benefits

  • Broad Range of Data Transfer Rates (from DC to 200Mbps)
  • Two Unidirectional Channels in the Same Direction (MAX12934) or Two Unidirectional Channels in the Opposite Direction (MAX12935)
  • SMA Connectors for Easy Connection to External Equipment
  • Wide Power Supply Voltage Range from 1.71V to 5.5V
  • Guaranteed Up to 5kVRMS Isolation (for the Wide-Body SOIC Package) for 60s

Product Detail

The MAX12934/MAX12935 evaluation kit (EV kit) provides a proven design to evaluate the MAX12934 or MAX12935 two channel, wide-body digital isolators.

The EV kit should be powered from two independent isolated power supplies with nominal output voltage in range from 1.71V to 5.5V. For evaluating the electrical parameters of the device without any isolation between the two sides, a single power supply can also be used.

The MAX1293XWEVKIT# comes with U1 populated and supports the following digital isolators: MAX12934BAWE+, MAX12934CAWE+, MAX12934EAWE+, MAX12934FAWE+, MAX12935BAWE+, MAX12935CAWE+, MAX12935EAWE+, MAX12935FAWE+

Applications

  • Multifunction printer
  • Sensor boards
  • Smart meter
