6.0 Mote Boot Up
6.1 Power-on Sequence
The M1030-2 mote has internal power on reset circuits that ensure that the mote will properly boot. However, for the power on
reset circuitry to function properly the external power supply must meet the timing shown in
Figure 4 and specified in
Table 10.
Figure 4 External Power Supply Timing Requirements
The following reset sequence (shown in Figure 5 and specified in Table 10) is required for external power supplies that fail to
meet the requirements above.
Figure 5 Power-on Sequence
6.2 Inrush Current
During power on, the mote can be modeled as a lumped impedance of 1 Ω and 27 μF, as shown in Figure 6. With a source
impedance (R
src
) of 1 Ω, the inrush current on the mote appears as shown in Figure 7.
