MP27942 2.5-5.5V Six-Channel Digital Isolator SOIC

MP27942 2.5-5.5V Six-Channel Digital Isolator SOIC

The MP27942 is a six-channel digital isolator that replaces a traditional optocoupler isolator in applications.

Typical Application Circuit

Applications

• Power Meters
• Programmable Logic Controllers (PLCs)
• Server Power
• Motor Controllers and Drivers
• Switches
• Solar Inverters

Design Notes

• The isolation rating is only valid if the PCB keeps the required creepage and clearance across the barrier — the package alone does not guarantee it.
• Common-mode transient immunity matters more than DC withstand in motor and gate-drive applications; check the dV/dt figure.
• Decouple both sides independently, with the capacitor returned to that side's ground.
• Propagation delay and pulse-width distortion set the timing margin in a closed loop.
