5. Technical Specifications
5.1. Power Supply
The GL6100 is supplied by an external DC voltage (Vin) that has a varied range and the GL6110 is
supplied by the USB Power, 5V DC.
The main regulation is made with an internal DC/DC converter in order to supply all the internal
functions with a DC voltage.
Refer to the following table for the GL61x0’s operating voltage range and maximum current.
Table 13. Power Supply Electrical Characteristics
GL61x0 Variant
Operating Voltage Range
Maximum Current
GL6100
4.75V to 32V DC, nominal at 12V
2.0A Peak at 4.75V
GL6110
As USB specify from 4.75V to 5.25V,
nominal at 5V
Limited Up to 500mA
5.1.1. GL6100 UART Version
For the GL6100, Vin ranges from +4.75V to +32V at 2.2A.
Refer to the following table for the consequences of supplying the GL6100 with too much or too little
voltage. Note that the correct operation of the GL6100 in connected mode is not guaranteed if the
input voltage falls below 4.75V.
Table 14. Effects of Power Supply Defect for the GL6100
If the voltage
Then
Falls below 4.75V
GSM communication is not guaranteed.
Is over 32V (transient peaks)
The GL6100’s protection is guaranteed by internal settings.
Is over 32V (continuous over voltage)
The GL6100’s protection is done by the fuse* (the supply voltage is
disconnected).
* The fuse is an 800mA/250V FAST-ACTING 5*20mm. The embedded fuse in the Adaptive Cable of the GL6100
is the FSD 800mA/250V FAST-ACTING.
Caution: The minimum input voltage specified here is the GL6100 input. Be mindful of the input voltage
decrease caused by the power cable. When using the cable that comes with the GL6100 packages,
this input drop is at around 800mV at 4.75V and 220mV at 32V.
The power supply must withstand a current peak of 2.8A in 4.75V input voltage. Refer to the Power
Consumption Tables in section 12 Power Consumption for more current information.
