Maxim Integrated’s digital isolators provide robust galvanic isolation for designers.
San Jose, CA—June 1, 2016—Designers can save space and achieve more flexible designs with theMAX14933 and MAX14937 two-channel, bi-directional digital isolators from Maxim Integrated Products, Inc. (NASDAQ: MXIM). They transfer digital signals between circuits in both directions and provide complete galvanic isolation between two power domains, all while using fewer components to save board space.
The MAX14933 and MAX14937 are the newest additions to Maxim’s recently introduced ultra-robust portfolio of quad-channel digital isolators, which include MAX14930–MAX14932 and MAX14934–MAX14936. These devices provide best-in-class speed, propagation delay, skew, and jitter for timing sensitive applications while maintaining an extremely robust isolation barrier between two power domains.
Digital isolators are replacing optocouplers in many applications because they offer the same isolation capabilities while using less board space and consuming less power. The MAX14933 and MAX14937 provide high voltage isolation of 2.75kVRMS or 5kVRMS, respectively. They support data rates from DC up to 1.7MHz and can be used in isolated I2C busses with or without clock stretching. Both products feature independent 2.25V to 5.5V supplies on each side of the isolator, and provide open-drain channels for applications that require data to be transmitted in both directions on the same line. Applications include power supplies, battery management systems, instrumentation, and interfaces for I2C, SMBus, or PMBus.
