The MPQ27821 is part of a 2-channel to 4-channel digital isolator family optimized to replace traditional optocoupler isolation in applications. It supports a data rate up to 50Mbps and 5V or 3.3V isolated power supply. The MPQ27821 uses capacitive isolation technology, supporting up to 3kVrms insulation voltage rating. This isolator provides small size, low power consumption, and higher reliability operation compared to traditional optocoupler isolators.
The MPQ27821 integrates one isolated DC/DC converter with up to 200mA output and 3kVRMS isolation, providing isolated power for the isolated data port. The MPQ27811 still provides Schmitt trigger input and isolation encoding/decoding for high immunity in noisy environments. The high/low selectable default failsafe output supports flexible design in application.
The MPQ27821 is available in a wide-body SOICW-16 package.
