20. I I I it l I f 5 2 1 2 12V input Source Power Supply Design Guidelines e 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 GC864 QUAD PY e When using a switching regulator a 500kHz or more switching frequency regulator is preferable because of its smaller inductor size and its faster transient response This allows the regulator to respond quickly to the current peaks absorption e For car PB battery the input voltage can rise up to 15 8V and this should be kept in mind when choosing components all components in the power supply must withstand this voltage e A Bypass low ESR capacitor of adequate capacity must be provided in order to cut the current absorption peaks a 100uF tantalum capacitor is usually suited e Make sure the low ESR capacitor on the power supply output usually a tantalum one is rated at least 10V e For Car applications a spike protection diode should be inserted close to the power input in order to clean the supply from spikes e A protection diode should be inserted close to the power input in order to save the GC864 QUAD PY from power polarity inversion This can be the same diode as for spike protection An example of switching re

Telit GC864 QUAD PY has a special function that reduces the power consumption during the idle time thus allowing a longer standby time with a given battery capacity This function monitors the DTR line indicating that the OEM application is ready to send commands when it goes high 3V on UART then the OEM application is not going to send any commands and the GC864 QUAD PY module can save energy by shutting down its internal serial port When the OEM application becomes again ready then the line DTR is tied low OV on UART the GC864 QUAD PY detects this condition and powers up the serial port If the power saving function is activated then the serial port must support the DTR line since when this line is high Data Terminal is NOT ready the device goes into a sleep condition and will not respond to commands until the DTR is tied low Data Terminal is ready NOTE The power saving function does not affect the network behavior of the GC864 QUAD PY even during the power save condition the module remains registered on the network and reachable for incoming calls or SMS If a call income during the power save then the module will wake up and proceed normally with the unsolicited incoming call code The DTR functionality is usable only when CFUN 5 is selected TIP When the GC864 QUAD PY wakes up from the sleep mode it takes a maximum of 150 milliseconds before it can exchange commands on the serial port Hence place a delay o
