Description
The MP27631 is a quad-channel digital isolator that replaces a traditional optocoupler isolator in applications. It can support up to 150Mbps of data rate signal isolation.
It employs capacitive isolation technology to provide up to 5kVRMS of insulation voltage. The MP27631 offers a compact solution, with low power consumption and improved reliability compared to traditional optocoupler isolators.
The device has a Schmitt trigger input as well as isolated encoding and decoding to reduce noise. The default high failsafe output can support a fixed output, even if the input signal power fails. The MP27631 is available in a wide SOICW-16 package.
