3kV rms Dual-Channel Digital Isolators
The ADuM128x 3 kV rms dual-channel family of digital isolators offers low propagation delays with data rates up to 100 Mbps. Unlike optocoupler alternatives, the ADuM128x family has a patented refresh feature that ensures DC correctness in the absence of input logic transitions. The ADuM1280 (2/0 channel directionality) and the ADuM1281 (1/1 channel directionality) have a default high output while the ADuM1285 (2/0 channel directionality) and the ADuM1286 (1/1 channel directionality) have a default low output.

Isolated Half-Bridge Gate Drivers with iCoupler Digital Isolator Technology Deliver Industry-best Speed and Reliability
The ADuM3223 and ADuM4223 are the fastest and most reliable isolated half-bridge gate drivers in the industry. These 4A gate drivers feature sub 55 ns propagation delays and less than 5 ns delay matching which is 4X faster than gate drivers designed using less effective optocoupler technology. The ADuM3223 and ADuM4223 meet safety standards for up to 5 kV rms reinforced isolation and have been designed to improve the performance and efficiency of AC-to-DC and DC-to-DC power supplies, solar-power inverters and motor control designs.

ezLINX: iCoupler Interface Development Environment
The plug-and-play ezLINX™ iCoupler® isolated interface development environment significantly reduces development time by enabling the evaluation of eight physical layer, digitally-isolated communication standards simultaneously (USB, RS-422, RS-485, RS-232, CAN, 2 x SPI, I²C, and LVDS). The tool was developed to assist embedded designers and system architects in designing and evaluating isolated communication interfaces using ADI's isolated interface transceivers with integrated iCoupler and isoPower® digital isolation technology.

Inside iCoupler Technology:
Implementing an Isolated Half-Bridge Gate Driver
An isolated half-bridge driver's function is to drive the gates of high-side and low-side N-channel MOSFETs (or IGBTs) with a low output impedance to reduce the conduction losses and a fast switching time to reduce the switching losses. The high-side and low-side drivers need very close matching of the timing characteristics to allow accurate and efficient switching. This reduces the deadtime from one switch of the half bridge turning off before the second switch turns on. A number of approaches have been used in the past, each involving the use of optocouplers to provide isolation; as this article describes, digital isolators integrated with gate drivers have significant benefits over these legacy approaches.
