Auto-Turning ON the GL865-DUAL/QUAD V3 To Auto-turn on the GL865-DUAL/QUAD V3, the power supply must be applied on the power pins VBATT and VBATT_PA, after 1000 m-seconds, the V_AUX / PWRMON pin will be at the high logic level and the module can be considered fully operating. When the power supply voltage is between 3.22V and 3.
PAGE 18
GL865-DUAL/QUAD V3 Hardware User Guide 1vv0301018 Rev.7 – 2013-10-30 NOTE: The power supply must be applied either at the same time on pins VBATT and VBATT_PA, or first applied on VBATT_PA and then on VBATT. The opposite sequence shall be avoided. The reverse procedure applies for powering down the module: first disconnect VBATT, then VBATT_PA, or both at once.

Rev.7 – 2013-10-30 Turning OFF the GL865-DUAL/QUAD V3 Turning off of the device can be done in two ways: • General turn OFF • Processor turn OFF General turn OFF – disconnect the power supply from the both power pins VBATT and VBATT_PA at the same time. In this case all parts of the module are in OFF condition, no power consumption is present.

GL865-DUAL/QUAD V3 Hardware User Guide 1vv0301018 Rev.7 – 2013-10-30 WARNING: POWERMON can be used to monitor only the power on but it cannot be used to monitor the power off because it remains high. Instead AT#SYSHALT works in the same way as previous GL865-DUAL/QUAD. NOTE: In order to prevent a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the GL865-DUAL/QUAD V3 when the module is powered off or during an ON/OFF transition.

GL865-DUAL/QUAD V3 Hardware User Guide 1vv0301018 6.3. Rev.7 – 2013-10-30 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. 6.3.1. Electrical Design Guidelines The electrical design of the power supply depends strongly on the power source from which this power is drained.

GL865-DUAL/QUAD V3 Hardware User Guide 1vv0301018 6.3.1.2. Rev.7 – 2013-10-30 + 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 GL865DUAL/QUAD V3.

GL865-DUAL/QUAD V3 Hardware User Guide 1vv0301018 6.3.1.3. Rev.7 – 2013-10-30 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 GL865-DUAL/QUAD V3 module.

GL865-DUAL/QUAD V3 Hardware User Guide 1vv0301018 6.3.2. Rev.7 – 2013-10-30 Thermal Design Guidelines The thermal design for the power supply heat sink should be done with the following specifications: See Par. 6.2 Power Consumption 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.

GL865-DUAL/QUAD V3 Hardware User Guide 1vv0301018 6.3.3. Rev.7 – 2013-10-30 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.
