6.0 Mote Boot Up
6.1 Power-on Sequence
The external supply and other power-on devices must provide the mote with a specific sequence of power and reset as follows:
Figure 3 Power-on Sequence
6.2 Inrush Current
During power on, the mote can be modeled as a lumped impedance of 1 Ohm and 2.5 µF, as shown in Figure 4. With a source
impedance (R
src
) of 2 Ohms, the inrush current on the mote appears as shown in Figure 5.
