I designed battery charger circuit with LT8708. The circuit is working correctly. Imon_INN, Imon_INP and Imon_ON pins also work as described in the datasheet. I'm just having trouble with the Imon_OP pin. Although my output current increases, the voltage value on imon_op pins doesn't change. So ı cant set current limiting on the output. No problems with connection and soldering on the circuit. I dont know the cause of problem. I will be glad if you help.
I measure the following values
Iout = 0.6 Amp , Vımon_op = 0.216 Volt Rsense = 2m ohm Rımon_op = 1.4 k
Iout = 1.2 Amp , Vımon_op = 0.216 volt Rsense =2m ohm Rımon_op = 1.4 k
