Choose the Power Supply for DIO302A

If the battery voltage is greater than 6V, DIO302A can not be directly powered by the battery. In this case if

there is a power supply from 1.9V to 6V in the system, then DIO302A can be powered by this power supply,

otherwise the circuit in Figure 8 can be used to generate the power supply for DIO302A. In Figure 8, resistor

R4 and R5 are used to generate a voltage between 1.9V to 6V to power DIO302A. R4 and R5 should be

chosen in such a way that the current flowing through R4 is larger than 15uA to meet DIO302A’s current
