New Domestic Isolation Chip!Sichuan Tumicro CA-Is372x Series Isolation Chips!

Have you ever encountered such problems when working on industrial control, motor drive, and new energy battery management systems?The communication speed is fast enough, but the anti-interference is not good, dropped the chain at a critical moment?The optocoupler delay is too large and the high-speed interface becomes a bottleneck？

It is often a small isolation chip that determines the stability and security of the entire system.So, is there a chip that combines high speed, low latency, and strong isolation?

Sichuan Tuwei CA-IS372x series, is a new choice for high-speed isolation.

CA-IS372x: A new choice for high-speed isolation

CA-IS372x seriesIt was launched by Shanghai Chuantu Micro (Chipanalog)High Speed Dual Channel Digital Isolator, is aHigh performance 2-channel digital isolator, with precise timing characteristics and low power consumption.Provides high electromagnetic immunity and low emissions.All device versionsBoth feature Schmitt trigger inputs for high noise immunity。for each isolation channelThe logic input and output buffers are isolated by silicon dioxide (SiO2) insulating gates.It can not only ensure high-speed data transmission, but also resist complex electromagnetic environments!
