Every application circuit must be properly designed to guarantee the correct functionality of the related interface, however a number of points require high attention during the design of the application device.

    See sections 2.2.1.3, 2.2.1.6, 2.2.1.8, 2.2.1.9 for specific design-in. If TOBY-L1 series modules are deployed in a mobile unit where no permanent primary supply source is available, then a battery will be required to provide VCC. A standard 3-cell Li-Ion or Li-Pol battery pack directly connected to VCC is the usual choice for battery-powered devices.
  • Page 38 Keep in mind that the use of batteries requires the implementation of a suitable charger circuit (not included in TOBY-L1 series modules). The charger circuit should be designed in order to prevent over-voltage on VCC beyond the upper limit of the absolute maximum rating. See section 2.2.1.7 for specific design-in.

    The power-on circuit (PWR_ON) requires careful layout, since it is the sensitive input available to switch on the TOBY-L1 series modules, once a valid VCC supply is provided beforehand. For the PWR_ON pin, ensure the voltage level is well defined during operation and no transient noise is coupled on this line, otherwise the module might detect an undesirable spurious power-on request.
