Hello,

Could you please let me know the maximum sink and source current of LED interface of DP83848K ?
Our customer requires these information for select the LED and designing the driver circuit.

The LED drivers should be able to operate safely with current drives of 5-10mA. They could actually supply more current than that, but the device was not designed with that level of high current demand in mind.

Hello Patrick san,

Thank you for the reply.

Is meaning of 5-10mA LED current range ?
Thus, maximum LED current for safely is 10mA.
