port, or Single Cell Li-Ion battery. Figure 38 shows the power system of OSD335x-SM including
connections between the PMIC and various power domains of the processor.
Table 2 shows the voltage output levels of each of the voltage sources which can be measured
on the respective test point. Each of the output voltages can be changed dynamically using I2C
commands when the PMIC is in active mode.
