Function Introduction
The GL2400/GL2401/GL2402 four-channel digital magnetic isolator is based on the independent isolation technology of Zhongke Geli Micro Technology Co., Ltd., and is designed using CMOS and MEMS technology. The device has excellent performance and can replace the optical coupler.
GL2400/GL2401/GL2402 is a four-channel digital isolator based on electromagnetic isolation, which can achieve complete electrical isolation between input and output. Both ends of the circuit are powered separately, and the power supply voltage from 3.0V to 5.5V can be used to work, and the 3V/5V level conversion can be realized. The four data channels are completely independent, and the data at the input end is high-frequency coded and the signal is recovered at the output end.
The circuit can withstand an isolation voltage of 5000V, and the common-mode transient immunity is greater than 25KV/µ s.
