ISO6760LNDWR Texas Instruments

Overview

The ISO6760L and ISO6760LN devices are high-performance, six-channel digital isolators with integrated interlock function for applications requiring up to 5000 V_RMS isolation ratings per UL 1577. These devices are also certified by VDE, TUV, CSA, and CQC.

The ISO6760L family of devices integrate a series of logic gates to provide hardware interlock functionality for adjacent channels. The interlock feature ensures that each channel, in a channel pairing, will not be enabled at the same time. If both channels in the pairing share the same input logic, the output logic will always be low. The ISO6760L family of devices have all six channels in the same direction and provide high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by TIs double capacitive silicon dioxide (SiO₂) insulation barrier.

Used in conjunction with intelligent power modules (IPMs), the interlock feature in these devices help prevent shoot through current between the high side and low side gate driver during turn on and turn off events. Six channels, including three pairings of interlock circuitry, are integrated in a 16-pin SOIC wide-body (DW) package with space savings greater than 50% compared to optocoupler solutions. Through innovative chip design and layout techniques, the electromagnetic compatibility of the ISO6760L devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance.

Wiki Reference

Optoelectronics, also known as optronics, is the field of study and application of electronic devices and systems that are used to detect, control, and manipulate light. It is often considered a subset of photonics. Optoelectronics encompasses the use of both visible light and invisible forms of radiation such as gamma rays, X-rays, ultraviolet, and infrared light. These devices can either convert electrical signals into optical signals, or vice versa. Optoelectronics relies on the quantum mechanical effects of light interacting with electronic materials, particularly semiconductors, often in the presence of electric fields. Key applications of optoelectronics include detecting and transmitting optical signals in various technologies.
