Setting OC and IST levels

In XDP710 FDM the current sense (CS) range and overcurrent (OC) level are set digitally by means of CS_RNG

bits in I_SNS_CFG PMBus command.

If required, the Non-RMS and RMS OC levels can be trimmed by CS_RNG_TRIM.

The start-up current limit (IST) through the FET is set digitally using dedicated START_ILIM bits in I_SNS_CFG

command:
