![]() ![]() The ISL71610M and ISL71710M both have significantly lower quiescent current than the competition, and the ISL71710M has nearly 4x lower dynamic current than Class V isolators. Both offer the New Space industry’s highest data rates-6x higher than competitive solutions-which make them ideal for serial communications links, such as RS-422, RS-485, and Controller Area Network (CAN). In serial communications subsystems that need the transmitter and receiver electrically isolated from each other, the ISL71610M operates up to 100 Mbps, and the ISL71710M up to 150 Mbps. In isolation partitioned power supply designs, the ISL71610M and ISL71710M provide an instantaneous 2.5kV RMS of isolation and 600V RMS continuous working voltage at 85☌. The Renesas GMR digital isolators are characterization tested at a total ionizing doze (TID) of up to 30krads(Si), and for single event effects (SEE) at a linear energy transfer (LET) of 43MeV Both GMR isolators also out-perform transformer-based digital isolators that experience electromagnetic interference (EMI) due to radiated emissions from edge and dipole radiation. Renesas’ Giant Magneto Resistive (GMR) digital isolators are ideal replacements for optocouplers that are susceptible to cloudy optics from total ionizing dose (TID) radiation. The passive input ISL71610M and active input ISL71710M offer superior performance across key electrical specifications, including isolation voltage, data rate, common mode transient immunity, propagation delay, quiescent current, and dynamic current. SmallSat mega-constellations provide ubiquitous broadband Internet of Things (IoT) communications anywhere across the globe, and Earth observation high-resolution imaging for sea, air, and land asset tracking. Private “New Space” companies plan to launch thousands of SmallSats forming large constellations that operate in multiple LEO planes. ![]() TOKYO, Japan ― Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced two plastic packaged, radiation-tolerant digital isolators that provide the highest isolation protection (2,500V RMS) from high voltage spikes in power supply stages and serial communications interfaces used in low Earth orbit (LEO) Small Satellites (SmallSats). ![]()
