The method for obtaining the maximum current is as follows:

The thermal resistance characteristics for the device are given in
under the following conditions:

FUSE_VDD
BATT_VDD
The FUSE_VDD rail is connected to ground. it only needs a voltage if the system fuse burning is needed.
1. Measure the worst case power consumption on individual rails using directed test on i.MX25.
2. Correlate the worst case power consumption power measurements with the worst case power
3. Combine common voltage rails based on the power supply sequencing requirements (add the

The values mentioned above should not be taken as a typical max run data
for specific use cases. These values are Absolute MAX data. Freescale
recommends that the system current measurements are taken with
customer-specific use-cases to reflect normal operating conditions in the
