Typical application diagram and pin description

This section describes two different application diagrams for the S2-LP. Figure 2:

"Suggested application diagram (embedded SMPS used)" shows the suggested

configuration with SMPS-ON.

Figure 2: Suggested application diagram (embedded SMPS used)

Figure 3: "Suggested application diagram (embedded SMPS not used)" shows the SMPS-

OFF mode application diagram, it allows to improve the sensitivity paying that with an

increasing of the power consumption.
