- Find out the full-scale range of
ISYS_IN pin in the VR14 controller.
- Set the VIREF to half
of the maximum voltage range of the ISYS_IN input of the VR14 controller. This
provides the necessary headroom and dynamic range for the system to accurately
monitor the load current up to the scalable fast-trip threshold (2 ×
IOCP).
- Calculate the value of
RIMON or RISYS using Equation 3 to set the appropriate over-current protection or circuit-breaker threshold
for eFuses.
- Finally, select the internal
scaling factor ISYS_IN_GAIN (set through the SVID_CONFIG) according to Equation 6.
