Hi
How I set the register to clamp output current ? Such as set the output current 25mA output, How i set the clamp current to 30mA or 20mA ?thanks

Hi Aggil,
Firstly, you need to set the CLEN bit to HIGH in DPS Register 1 (Address 0x2).
Then, change the DAC setting for the low clamp level (CLL) and high clamp level (CLH) on addresses 0xD and 0x10 respectively. Please note that ICLL cannot have positive value while ICLH cannot have a negative value due to the fixed sign bit on their DAC value.
Finally, from the datasheet below, the transfer function for the current clamp is given. I have also added below the DAC Code equation for ease of computation.
Best Regards,
DJ
