Functional Description:

TDA51S-41HC is a family of high-performance reinforced digital isolators with an integrated isolated DC-DC converter. TDA51S-41HCeliminatetheneed for a separate, isolated power supply, which results in a small form factor, total isolation solution. TDA51S-41HC device has three forward and one reverse-direction channels, and it has fail-safe mode option. If the input signal islost, defaultoutput is low for devices with H. In addition, other channel communication types, such as two forward channels and two reverse channels, four forwardchannels, four reverse channels, and many other channel combination types are under development.

Features:

 Ultra-small, ultra-thin, chip scale SOIC package

 Baud rate up to 100Mbps

 Wide input supply range: 3.15 V to 5.5 V

 High isolation to 5000Vrms

 Nanosecond propagation delay

 Integrated overload, short-circuit protection and thermal shutdown

 High CMTI: 150 kV/μs (typical)
