ME910C1 HW User Guide 4. 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. Power Supply Requirements The external power supply must be connected to VBATT & VBATT_PA signals and must fulfil the following requirements: Power Supply Value Nominal Supply Voltage 3.
ME910C1 HW User Guide NOTE: The Operating Voltage Range MUST never be exceeded; care must be taken when designing the application’s power supply section to avoid having an excessive voltage drop. If the voltage drop is exceeding the limits it could cause a Power Off of the module. The Power supply must be higher than 3.10 V to power on the module.

ME910C1 HW User Guide NOTE: The reported values are an average among all the product variants and bands for each network wireless technology. The support of specific network wireless technology depends on product variant configuration. 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. 4.3.1.
ME910C1 HW User Guide An example of linear regulator with 5V input is: Guidelines 4.3.1.2. +12V 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.
ME910C1 HW User Guide An example of switching regulator with 12V input is in the below schematic: 4.3.1.3. 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 ME910C1 module.
ME910C1 HW User Guide NOTE: DON'T USE any Ni-Cd, Ni-MH, and Pb battery types directly connected with ME910C1. Their use can lead to overvoltage on the ME910C1 and damage it. USE ONLY Li-Ion battery types. 4.3.2. Thermal Design Guidelines Worst case as reference values for thermal design of ME910C1 are: Average current consumption: 800 mA Supply voltage: 3.80V NOTE: Make PCB design in order to have the best connection of GND pads to large surfaces.
ME910C1 HW User Guide A misplaced component can be useless or can even decrease the power supply performances. The Bypass low ESR capacitor must be placed close to the Telit ME910C1 power input pads or in the case the power supply is a switching type it can be placed close to the inductor to cut the ripple provided the PCB trace from the capacitor to the ME910C1 is wide enough to ensure a dropless connection even during an 0.8 A current peak.
ME910C1 HW User Guide The insertion of EMI filter on VBATT pins is suggested in those designs where antenna is placed close to battery or supply lines. A ferrite bead like Murata BLM18EG101TN1 or Taiyo Yuden P/N FBMH1608HM101 can be used for this purpose. The below figure shows the recommended circuit: VAUX Power Output A regulated power supply output is provided in order to supply small devices from the module.

ME910C1 HW User Guide 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 ME910C1 power regulator and improper power on/off of the module. The line ON_OFF* must be connected only in open collector or open drain configuration. In this document all the lines that are inverted, hence have active low signals are labelled with a name that ends with”#",”*” or with a bar over the name.
ME910C1 HW User Guide A flow chart showing the proper turn on procedure is displayed below: “Modem ON Proc” START N VBATT > 3.10V ? Y Y PWRMON=ON ? N ON_OFF* = LOW GO TO “HW Shutdown Unconditional” Delay = 5 sec (see note below) ON_OFF* = HIGH PWRMON=ON ? N Y Delay = 1 sec GO TO “Start AT Commands”” “Modem ON Proc” END When the USB is connected or after the firmware updating, Delay must be equal at least to 10 seconds. 1VV0301351 Rev.
ME910C1 HW User Guide A flow chart showing the AT commands managing procedure is displayed below: “Start AT CMD” START Delay = 300 msec Enter AT AT answer in 1 sec ? GO TO “HW Shutdown Unconditional” N Y GO TO “Modem ON Proc.” “Start AT CMD” END NOTE: In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the ME910C1 when the module is powered off or during an ON/OFF transition. 1VV0301351 Rev.
ME910C1 HW User Guide For example: 1- Let's assume you need to drive the ON_OFF* pad with a totem pole output of a +3/5 V microcontroller (uP_OUT1): 2- Let's assume you need to drive the ON_OFF* pad directly with an ON/OFF button: 1VV0301351 Rev.
ME910C1 HW User Guide WARNING It is recommended to set the ON_OFF* line LOW to power on the module only after VBATT is higher than 3.10V. In case this condition it is not satisfied you could use the HW_SHUTDOWN* line to recover it and then restart the power on activity using the ON_OFF * line. An example of this is described in the following diagram. Power ON diagram: After HW_SHUTSDOWN* is released you could again use the ON_OFF* line to power on the module. 1VV0301351 Rev.
ME910C1 HW User Guide Power Off Turning off of the device can be done in two ways: • via AT command (see ME910C1 Software User Guide, AT#SHDN) • by tying low pin ON_OFF* Either ways, the device issues a detach request to network informing that the device will not be reachable any more. To turn OFF the ME910C1 the pad ON_OFF* must be tied low for at least 3 seconds and then released. NOTE: To check if the device has been powered off, the hardware line PWRMON must be monitored.
ME910C1 HW User Guide The following flow chart shows the proper turn off procedure: “Modem OFF Proc.” START PWRMON=ON? N Y AT Key OFF Mode ON_OFF* = LOW Delay >= 3 sec AT#SHDN ON_OFF* = HIGH PWRMON=ON? N “Modem OFF Proc.” END Y N Looping for more than 15s? Y GO TO “HW SHUTDOWN Unconditional” 1VV0301351 Rev.
ME910C1 HW User Guide Unconditional Shutdown HW_SHUTDOWN* is used to unconditionally shutdown the ME910C1. Whenever this signal is pulled low, the ME910C1 is reset. When the device is reset it stops any operation. After the release of the line, the ME910C1 is unconditionally shut down, without doing any detach operation from the network where it is registered. This behaviour is not a proper shut down because any WCDMA device is requested to issue a detach request on turn off.
ME910C1 HW User Guide For example: Let us assume you need to drive the HW_SHUTDOWN* pad with a totem pole output of a +3/5 V microcontroller (uP_OUT2): NOTE: In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the ME910C1 when the module is powered off or during an ON/OFF transition. In the following flow chart is detailed the proper restart procedure: 1VV0301351 Rev.
ME910C1 HW User Guide “HW SHUTDOWN Unconditional” START HW_SHUTDOWN* = LOW Delay = 1s Delay = 200ms Disconnect VBATT HW_SHUTDOWN* = HIGH Y PWRMON = ON N “HW SHUTDOWN Unconditional” END NOTE: Do not use any pull up resistor on the HW_SHUTDOWN* line nor any totem pole digital output. Using pull up resistor may bring to latch up problems on the ME910C1 power regulator and improper functioning of the module.
ME910C1 HW User Guide Fast power down The procedure to power off ME910C1 described in Chapter 5.3 normally takes more than 1 second to detach from network and make ME910C1 internal filesystem properly closed. In case of unwanted supply voltage loss the system can be switched off without any risk of filesystem data corruption by implementing Fast Shut Down feature. Fast Shut Down feature permits to reduce the current consumption and the time-topoweroff to minimum values.
ME910C1 HW User Guide NOTE: In case of power on with slow ramp-up of Vbatt supply voltage while ON/OFF* is tied to GND (case possibile if timing are not properly controlled), HW_SHUTDOWN* line has to be used according to power on diagram in chapter 5.2. NOTE: Consider voltage drop under max current conditions when defining the voltage detector thereshold in order to avoid unwanted shutdown. Tipical timings are reported in the plot above when testing the example circuit with Ctank=47mF.
ME910C1 HW User Guide where 80mA is a typical current during fast shut down procedure, 300ms is the typical time to execute the shutdown and 0.5V is the minimum voltage marging from threshold of ME910C1 hardware reset. TIP: Make the same plot during system verification to check timings and voltage levels. 5.5.2. Fast Shut Down by Software The Fast Power Down can be triggered by AT command. 1VV0301351 Rev.
