Supply Voltage Ranges
Table 2: Supply voltage ranges
Following voltages are assumed as normal and extreme voltages for used battery:
Table 3: Battery voltages
1 TA will test with the nominal voltage at an 85% range (0.85 x 3.7V = 3.145V); therefore the
nominal voltage has been set to 3.8V. ADC settings in the SW might shutdown the phone
above the min value. During fast charging of an empty battery, the max voltage might exceed
this value. Voltages between 4.20 and 4.60 might appear for a short while.
