Amid the waves of Industry 4.0, smart vehicles and the energy revolution, digital isolators, as the "core defense line" of electrical safety, directly determine the system's anti-interference ability, data transmission reliability and the safety of personnel and equipment. As a globally renowned electronic distributor, Shenzhen Mingjiada Electronics Co., Ltd. relies on a inventory of tens of millions of yuan in stock and a vertical technical service system. It supplies the full range of digital isolators as core products (onsemi), providing genuine products from the original factory and one-stop supply services to empower enterprises to overcome safety isolation challenges in high-noise environments!
1. Mingjiada supplies onsemi digital Isolator matrix: Leading technology, covering all scenario demands
1. High-speed bidirectional isolator: Breaking the bottleneck of communication rate
Representative models: NCID9210/NCID9211
Core technology
Full-duplex bidirectional communication, with a data rate as high as 50 Mbps and a transmission delay as low as 17 ns
The thickness of the external capacitor isolation layer is ≥0.5mm (25 times more than the traditional solution), and the insulation reliability is on par with that of optocouplers
With a common-mode rejection ratio of 100 kV/μs, it completely eliminates the noise interference from the start and stop of industrial motors and the switching of on-board inverters
Typical scenarios: Industrial fieldbus (CAN/RS-485), in-vehicle Ethernet gateway
2. Automotive-grade multi-channel isolator: Driving electrical safety in new energy vehicles
Representative models: NCID9401/NCID9411
Core technology
It complies with AEC-Q100 standards, supports PPAP processes, and has a temperature range of -40°C to +125°C
▶ Four-channel configuration, integrated output enable control, simplifying BMS battery sampling isolation and redundant design of the electric drive system
▶ 5000 Vrms isolation withstand voltage (UL1577 certified), providing a safety barrier for 800V high-voltage platforms
Typical scenarios: OBC (on-board charger), traction inverter, domain controller for new energy vehicles
3. Highly integrated isolated gate driver: Reinventing the power control system
Representative model: TLP5702 (onsemi Compatible solution)
Core technology
▶ Peak drive current 2.5A, switching delay 0.5 μs, specifically optimized for SiC/GaN power devices
▶ Integrated desaturation protection (DESAT) to prevent IGBT pass-through faults
Typical scenarios: Photovoltaic inverters, servo drives, charging piles
