Description

Digital isolators offer significant, compelling advantages over optocouplers in terms of size, speed, power consumption, ease of use, and reliability. For years, designers of industrial, medical, and other isolated systems had limited options when implementing safety isolation: the only reasonable choice was the optocoupler. Today, digital isolators offer advantages in performance, size, cost, power efficiency, and integration. Designers incorporate isolation because of safety regulations or to reduce noise from ground loops, etc. Galvanic isolation ensures data transfer without an electrical connection or leakage path that might create a safety hazard. Yet, isolation imposes constraints such as delays, power consumption, cost, and size. A digital isolator’s goal is to meet safety requirements while minimizing incurred penalties.

The MAX2256XAEVKIT# is a kit for evaluating the MAX22563 through the MAX22566, a family of reinforced, six-channel, galvanic digital isolators in a 20-pin SSOP package. It features ADI's Reinforced, Fast, Low-Power, Six-Channel Digital Isolators which have two isolation barriers in series, separate isolation barriers on each die, and meet VDE and UL reinforced standards.

The MAX2256XAEVKIT# is a generic board that comes with U1 unpopulated and supports the following digital isolators: MAX22563BAAP+, MAX22563CAAP+, MAX22564BAAP+, MAX22564CAAP+, MAX22565BAAP+, MAX22565CAAP+, MAX22566BAAP+, and MAX22566CAAP+.

The key differences of the digital isolator chips are:

The evaluation board supports the 20-pin SSOP package type only. The MAX22163−MAX22166 and MAX22663−MAX22666 are functionally equivalent to MAX22563−MAX22566, but in different package types. The MAX22163−MAX22166 come in a 16-pin QSOP and MAX22663−MAX22666 in a 16-pin wide SOIC package.

The EV kit can be used to evaluate the functionality and electrical performance of the entire family of the devices. The EV kits should be powered from two independent isolated power supplies with nominal output voltage in the range from 1.71V to 5.5V. To evaluate the electrical parameters of the device without any isolation between the two sides, a single power supply can also be used.

Roadtester Instructions

1. Working with the documentation, open the box and test the out of the box experience of the eval kit.
2. Solder the applicable part to the board and report on your experience
3. Show the reader of this review what you discovered about the eval kit through text, images, videos, and/or any other media, so the reader understands what is involved in using the product.

4. You can also test it more in depth with your review spanning, signal integrity, power integrity, noise coupling and high voltage testing. The main features that should be called out are as follows:

   • High Channel Density ( 6 isolated channels available in multiple forward/reverse configurations.)
   • Edge based differential architecture ( Capacitive Isolation Technology) enabling:
     • Low Propagation Delay  (7ns )
     • Low Jitter  (11.1ps)
     • Low power consumption per channel (34mW per Channel at 1Mbps with VDD = 3.3V)
   • Highest Data Rate (200Mbps)
   • VISO = 3.75kVrms, VIOWM = 784 Vrms

   CMTI = 50kV/us
