The maximum current that can be drained from the ON# pad is 0,1 mA. A simple circuit to do it is: NOTE: Don't use any pull up resistor on the ON_OFF* line, it is internally pulled up. Using pull up resistor may bring to latch up problems on the HE910 power regulator and improper power on/off of the module.

HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 5 Power Supply The power supply circuitry and board layout are a very important part in the full product design and they strongly reflect on the product overall performances, hence read carefully the requirements and the guidelines that will follow for a proper design. 5.

HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 5.3 General Design Rules The principal guidelines for the Power Supply Design embrace three different design steps: the electrical design the thermal design the PCB layout. 5.3.1 Electrical Design Guidelines The electrical design of the power supply depends strongly from the power source where this power is drained.
PAGE 33
HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 An example of linear regulator with 5V input is: 5.3.1.2 + 12V input Source Power Supply Design Guidelines The desired output for the power supply is 3.8V, hence due to the big difference between the input source and the desired output, a linear regulator is not suited and shall not be used. A switching power supply will be preferable because of its better efficiency especially with the 2A peak current load represented by the HE910.
PAGE 34
HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 A protection diode should be inserted close to the power input, in order to save the HE910 from power polarity inversion. This can be the same diode as for spike protection. An example of switching regulator with 12V input is in the below schematic: Reproduction forbidden without Telit Communications S.p.A.
PAGE 35
HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 5.3.1.3 Battery Source Power Supply Design Guidelines The desired nominal output for the power supply is 3.8V and the maximum voltage allowed is 4.2V, hence a single 3.7V Li-Ion cell battery type is suited for supplying the power to the Telit HE910 module. WARNING: The three cells Ni/Cd or Ni/MH 3,6 V Nom.
PAGE 36
HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 5.3.2 Thermal Design Guidelines The thermal design for the power supply heat sink should be done with the following specifications: Average current consumption during HSDPA transmission @PWR level max : 600 mA Average current during idle: 1.5 mA NOTE: The average consumption during transmissions depends on the power level at which the device is requested to transmit by the network. The average current consumption hence varies significantly.
PAGE 37
HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 5.3.3 Power Supply PCB layout Guidelines As seen on the electrical design guidelines the power supply shall have a low ESR capacitor on the output to cut the current peaks and a protection diode on the input to protect the supply from spikes and polarity inversion. The placement of these components is crucial for the correct working of the circuitry. A misplaced component can be useless or can even decrease the power supply performances.

HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 6.5 GPS Antenna Requirements (HE910 and HE910-GA) The HE910 module is already provided with an internal LNA amplifier so it is also possible to develop an application including a passive Antenna. The use of an active antenna is required to achieve a better performance especially when the GPS antenna distance from the module is quite high. The module is provided of a Digital Output signal to enable the external LNA (pad R7) 6.5.
PAGE 44
HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 When using the Telit HE910, since there is no antenna connector on the module, the antenna must be connected to the HE910 through the PCB with the antenna pad. In the case that the antenna is not directly developed on the same PCB, hence directly connected at the antenna pad of the HE910, then a PCB line is needed in order to connect with it or with its connector.
PAGE 45
HE910 Hardware User Guide 1vv0300925 Rev.9 – 07-02-2012 If you do not have EM noisy devices around the PCB of HE910, use a stripline on the superficial copper layer for the antenna line. The line attenuation will be lower than a buried one. 6.5.5 GPS Antenna - Installation Guidelines The HE910 due to its characteristics of sensitivity is capable to perform a Fix inside the buildings. (In any case the sensitivity could be affected by the building characteristics i.e. shielding).

This level translator must: invert the electrical signal in both directions; Change the level from 0/1.8V to +15/-15V.

If the digital output of the device to be connected with the GPIO input pad has interface levels different from the 1.8V CMOS, then it can be buffered with an open collector transistor with a 47K pull up to 1.8V.
