i try to use the ADN8810 ( current driver) to control a lens that required 300mA. i used the fig 1 of the data sheet encomp is set to gnd . /Reset and /SB to dvdd ( 5V) , Pvdd is set to 3.3V , vref to 4.096V using LM4128 and the spi is coming from a µcontroller, the 3 signal looks ok i also check the clock rising edge on the /CS.


the Fault signal is always at 5V and the Iout is at 86mA without any change.



if anyone have an idea......... thankssssssssss
