Power Distribution Switches, Load Drivers FAQ

How does the VN808CM-E handle overload conditions?

The device employs active current limitation and thermal shutdown. In overload, the affected channel turns off and automatically restarts to maintain junction temperature. If case temperature exceeds limits, the channel remains off until cooling occurs.

What logic voltage levels are supported?

The VN808CM-E accepts 3.3 V CMOS-compatible logic signals, allowing direct connection to microcontrollers without additional level shifting circuitry.

Is there protection against ground loss?

Yes, the device automatically turns off all channels if the ground pin is disconnected, preventing potential damage or unsafe operation.
