ME910C1 HW User Guide General Design Rules The principal guidelines for the Power Supply Design embrace three different design steps: the electrical design of the power supply the thermal design the PCB layout 4.3.1. Electrical Design Guidelines of the power supply The electrical design of the power supply depends strongly from the power source where this power is drained.
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: 250 mA (LTE CAT M1 and NB1 modes) Average current consumption: 600 mA (GPRS and EDGE modes) Supply voltage: 4.
ME910C1 HW User Guide ME910C1 is wide enough to ensure a dropless connection even during an 0.6 A (LTE) or 2A (GSM) current peak. The protection diode must be placed close to the input connector where the power source is drained. The PCB traces from the input connector to the power regulator IC must be wide enough to ensure no voltage drops occur when an 2 A current peak is absorbed (valid only for product supporting GSM mode).

ME910C1 HW User Guide NOTE: Don't use any pull up resistor on the ON_OFF*/WAKE* 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*/WAKE* 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>3.20V? Y Y PWRMON=ON ? N ON_OFF*/WAKE* = LOW KEEP LOW = 6 sec (see note below) GO TO “HW Shutdown Unconditional” ON_OFF*/WAKE*= HIGH PWRMON=ON ? N Y Delay = 2 sec GO TO “Start AT Commands”” “Modem ON Proc” END 1VV0301351 Rev.
ME910C1 HW User Guide NOTE: The ON_OFF*/WAKE* can be kept low for 5 instead of 6 secs and delays to start AT commands reduced to 1s on following SW releases: 30.00.xx2 30.00.xx3 30.00.xx4 A flow chart showing the AT commands managing procedure is displayed below: “Start AT CMD” START Delay = 300 msec Enter AT AT answer in 6 sec ? N GO TO “HW Shutdown Unconditional” Y GO TO “Modem ON Proc.” “Start AT CMD” END 1VV0301351 Rev.
ME910C1 HW User Guide NOTE: Waiting time for the AT commands answer can vary between different ME910C1 variants, between 2-6 sec. 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*/WAKE* 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*/WAKE* pad directly with an ON/OFF button: 1VV0301351 Rev.
ME910C1 HW User Guide WARNING It is recommended to set the ON_OFF*/WAKE* line LOW to power on the module only after VBATT is higher than 3.20V. 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*/WAKE* line. An example of this is described in the following diagram. After HW_SHUTDOWN* is released you could again use the ON_OFF*/WAKE* line to power on the module.
ME910C1 HW User Guide WARNING: Not following the recommended shut-down procedures might damage the device and consequently void the warranty. The following flow chart shows the proper turn off procedure: “Modem OFF Proc.” START PWRMON=O N? N Y AT OFF Mode Key ON_OFF*/WAKE* = LOW Delay >= 3 sec AT#SHDN ON_OFF*/WAKE* = HIGH PWRMON=O N? N “Modem OFF Proc.” END Y N 1VV0301351 Rev.
ME910C1 HW User Guide Wake from deep sleep mode ME910C1 supports Power Saving Mode (PSM) functionality defined in 3GPP Release 12. When Periodic Update Timer expires, ME910C1 power off until the next scheduled wakeup time. Asynchronous event controlled by host can wake up from deep sleep mode by asserting ON_OFF*/WAKE* pin LOW for at least 5 seconds. Host can detect deep sleep mode by polling VAUX/PWRMON pin if previously configured.

It shall be kept as an emergency exit procedure. A typical circuit is the following: 1VV0301351 Rev.
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): In the following flow chart is detailed the proper restart procedure: 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 “HW SHUTDOWN Unconditional” START HW_SHUTDOWN* = LOW Delay = 1s Delay = 200ms Disconnect VBATT HW_SHUTDOWN* = HIGH PWRMON = ON Y 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: Consider voltage drop under max current conditions when defining the voltage detector thereshold in order to avoid unwanted shutdown. The capacitor is rated with the following formula: TIP: Make the same plot during system verification to check timings and voltage levels. 5.6.2. Fast Shut Down by Software The Fast Power Down can be triggered by AT command. Forced USB boot If standard firmware upgrade procedures are not possible, FORCED_USB_BOOT pin must be set to 1.
