Novosense Microelectronics Products

Novosense offers four main product categories: Digital Isolators featuring single to multi-channel configurations with isolation ratings up to 5kVrms. Isolated Gate Drivers designed for SiC MOSFET and IGBT applications with drive currents from 2A to 6A. Isolated Transceivers including RS-485, RS-232, and CAN with integrated isolation barriers. Signal Chain Products including precision op-amps, instrumentation amplifiers, current sense amplifiers, and temperature sensors. Each category serves specific application needs in industrial, automotive, and power supply markets.

Selecting the right digital isolator requires considering several key parameters: First, isolation voltage requirement - choose 3.75kVrms standard for 240V equipment, or 5kVrms reinforced for 480V or medical equipment. Second, channel configuration - select from 1-channel to 6-channel options based on signal count requirements. Third, data rate - choose 1Mbps for standard industrial signals, 10Mbps for SPI/SDIO interfaces, or 150Mbps for high-speed UART/FlexRay. Fourth, package - SOP for standard applications, TSSOP for space-constrained designs, or DFN for ultra-compact solutions. Fifth, certification requirements - UL1577 required for safety applications, IEC 60747-5-5 for reinforced insulation. Contact BeiLuo FAE for detailed selection assistance.

Define your isolation voltage, channel count, and data rate requirements first. Use Novosense parametric search tool or contact BeiLuo for specific product recommendations matching your parameters.

Standard isolation (3.75kVrms rated) provides basic isolation suitable for most industrial equipment operating at 240V AC or below. Reinforced isolation (5kVrms rated) provides enhanced safety margins required for 480V equipment, medical devices, and applications where single fault safety is critical. Reinforced isolators undergo stricter testing including input-output safety testing per IEC 60747-5-5 standard. The key difference is that reinforced isolation uses thicker isolation barriers (typically >21um SiO2) versus standard (>13um). This results in higher working voltage ratings (1.5kVrms vs 600Vrms) and improved reliability (>50-year lifetime). For equipment requiring double insulation or reinforced insulation per IEC 62368-1, choose reinforced isolation products.

For 480V equipment, medical devices, or applications requiring reinforced insulation, select Novosense NSi81xx series. For standard 240V industrial equipment, NSi82xx series provides adequate isolation with cost optimization.

Novosense isolated gate drivers offer comprehensive features for power converter applications: High drive capability with 2A to 6A source/sink currents suitable for SiC MOSFETs and IGBTs from 10A to 600A. Fast propagation delay under 100ns enabling switching frequencies up to 1MHz for high-efficiency converters. High CMTI exceeding 150kV/us ensuring reliable operation in high dv/dt environments typical of SiC applications. Integrated protection features including UVLO (under-voltage lockout) with hysteresis, desaturation detection, soft turn-off, and active Miller clamp. Wide temperature range from -40C to +125C meeting automotive and industrial requirements. Multiple isolation ratings and package options for design flexibility. The drivers use proprietary magnetic coupling technology providing excellent common-mode rejection and long-term reliability.

For SiC MOSFET applications, choose NSi6602 with 4A/6A drive capability. For IGBT applications below 300A, use NSi6230. For high-power IGBT modules requiring 5A drive, select NSi6238. Contact FAE for thermal design support.

Novosense isolated RS-485 transceivers integrate isolation technology directly into the transceiver IC, providing several advantages over discrete solutions: Simplified design with fewer external components (no need for external digital isolators and isolated DC-DC converters). Reduced board space by 30-50% compared to discrete isolation solutions. Lower total system cost when considering component count, PCB area, and assembly. Improved reliability with single vendor qualification and integrated testing. Consistent performance across temperature and lifetime versus discrete solutions with separate isolators and regulators. Enhanced ESD protection with integrated TVS diodes on bus lines. Available in standard (3.75kVrms) and reinforced (5kVrms) isolation versions for different application requirements.

For new industrial RS-485 designs requiring isolation, choose Novosense NSi84xx isolated transceivers for simplified design and lower total cost. For existing designs using discrete isolation, the pin-compatible isolated transceivers offer easy upgrade path.
