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
Our apologies, the ADN8810 is no longer supported on EngineerZone. Please contact our support center for assistance.
I would like to know, if you were able to solve the issue?
The reason why I'm asking is because I have a similar problem.
And please correct me if I'm wrong, but don't you have to use the FB Pin as output in this configuration?
