SHUNT resistances

Not open for further replies.
Hi,

I'm trying to create a Driver circuit for a laser diode stack (see attached diagram)

To adjust the power of the laser stack, on pin 3 of the operational IC3, using a voltage ranging from 0 to 4V, I adjust the maximum current that the driver can supply.

With the R1 trimmer I carry out the calibration.

+ Vo1 and + Vo2 = + 12Vdc
-Vo1 and -Vo2 = -12Vdc
On V + and V- there are 24Vdc
On LD + and LD- the laser diode stack is connected, it can have a maximum absorption of 60 amps for a few milliseconds e.g. 30ms.

If you kindly give me some advice on the value of the SHUNT resistances (R25, R24, R23, R22) to use ...

is 0.1 ohm 10Watt ok?
