ISO1212: Output current limit (for LEDs)

Part Number: ISO1212

I notice from one of the reference designs you current limit the output driving the LED to 1.7mA on the ISO1212.  But I can not find the output current limit in the datasheet. Which parameter is it in the datasheet or what is the output current limit for driving an LED like the reference design?

Thanks,

-Tim

  • Tim,

    Which reference design are you referring to? Do you mean the LED driving application circuit from Figure 26 of the data sheet? Additionally the Absolute Maximum output current of the ISO1212 is 15mA. Current limiting for an LED would generally be achieved by a current limiting resistor like the one from Figure 26.
