The Fault trigger does not respond properly

Category: Hardware
Product Number: MAX22205

Hi,
In my circuit I use a MAX22205ATU+ driver to drive a DC motor.
I calibrated the output signal to a PWM signal with a frequency of 8kHz. Everything works well but when I put a little load and the current reaches up to ~2A, then the Fault signal drops to logical 0 for several times.

I have ISET3=0, ISET2=1, ISET1=1, ISET0=0, Rref=20kohm, Roff=100kohm.


How can I adapt the Fault threshold to a higher current value? (say 5A)

Thanks, 

Idan
