OR Controllers, Ideal Diodes FAQ

Can the current limit be adjusted on both channels independently?

Yes, each diode has its own current limit pin (CLIM1 and CLIM2) allowing independent adjustment up to the internal limit.

What is the purpose of the PRIORITY setting?

The PRIORITY setting allows the device to automatically switch over between inputs when the proper input voltage threshold on IN1 is achieved.
