Smart Machine Smart DecisionSIM7600V-H_User Manual_V1.00 2018-02-24203Interface Application3.1 Power SupplyOn VBAT pads, a ripple current up to 2A typically, may cause voltage drop. Therefore, the powersupply for these pads must be able to provide sufficient current up to more than 2A in order toavoid the voltage drop of more than 300mV.Table 6: VBAT Pins electronic characteristicSymbolDescriptionMin.Typ.Max.UnitVBATModule power voltage3.43.84.2VIVBAT(peak)Module power peak current in normal mode.1.0-2AIVBAT(average)Module power average current in normal modePlease refer to the table 34IVBAT(sleep)Power supply current in sleep modeIVBAT(power-off)Module power current in power off mode.--20uA3.1.1 Power supply Design GuideMake sure that the voltage on the VBAT pins will never drop below 3.4V.Note: If the power supply for BAT pins can support up to 2A, using a total of more than 220uFcapacitors is recommended, or else users must use a total of 1000uF capacitors, in order to avoidthe voltage drop of more than 300mV.Some multi-layer ceramic chip (MLCC) capacitors (0.1/1uF) with low ESR in high frequency bandcan be used for EMC.These capacitors should be put as close as possible to VBAT pads. Also, user should keep VBATtrace on the circuit board wider than 2 mm to minimize PCB trace impedance. The following figureshows the recommended circuit.Figure 5: Power supply application circuit
Smart Machine Smart DecisionSIM7600V-H_User Manual_V1.00 2018-02-2421In addition, in order to guard over voltage protection, it is suggested to use a zener diode with 5.1Vreverse zener voltage and more than 500mW power dissipation.Table 7: Recommended zener diode listNo.ManufacturerPart Numberpower dissipationPackage1On semiMMSZ5231BT1G500mWSOD1232PrisemiPZ3D4V2H500mWSOD3233VishayMMSZ4689-V500mWSOD1234CrownpoCDZ55C5V1SM500mW08053.1.2 Recommended Power Supply CircuitIt is recommended that a switching modepower supply or linear regulator power supply is used. Itis important to make sure that all the components used in the power supply circuit can resist a peakcurrent up to 2A.The following figure shows the linear regulatorreference circuit with 5V input and 3.8V output.Figure 6: Linear regulator reference circuitIf there is a big voltage difference between input and output for VBAT power supply, ortheefficiency is extremely important,then a switching mode power supply will be preferable. Thefollowing figure shows theswitching mode power supply reference circuit.Figure 7: Switching modepower supply reference circuitNote: The Switching Mode power supply solution for VBAT must be chosen carefully againstElectro Magnetic Interference and ripple current from depraving RF performance.
Smart Machine Smart DecisionSIM7600V-H_User Manual_V1.00 2018-02-24223.1.3 Voltage MonitorTo monitor the VBAT voltage, the AT command “AT+CBC” can be used.For monitoring the VBAT voltage outside or within a special range, the AT command“AT+CVALARM” can be used to enable the under-voltage warning function.If users need to power off Module, when the VBAT voltage is out of a range, the AT command“AT+CPMVT” can be used to enable under-voltage power-off function.Note: Under-voltage warning function and under-voltage power-off function are disabled bydefault. For more information about these AT commands, please refer to Document [1].3.2 Power on/Power off/Reset Function3.2.1 Power onModule can be powered on by pulling the PWRKEY pin down to ground.The PWRKEY pin has been pulled up to dVDDinternally, so you does not need to pull it upexternally.

Safety CautionTable 42: Safety cautionMarksRequirementsWhen in a hospital or other health care facility, observe the restrictions about the useof mobiles. Switch the cellular terminal or mobile off, medical equipment may besensitive and not operate normally due to RF energy interference.Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it isswitched off. The operation of wireless appliances in an aircraft is forbidden toprevent interference with communication systems. Forgeting to think much of theseinstructions may impact the flight safety or offend local legal action, or both.Do not operate the cellular terminal or mobile in the presence of flammable gases orfumes. Switch off the cellular terminal when you are near petrol stations, fuel depots,chemical plants or where blasting operations are in progress. Operation of anyelectrical equipment in potentially explosive atmospheres can constitute a safetyhazard.Your cellular terminal or mobile receives and transmits radio frequency energy whileswitched on. RF interference can occur if it is used close to TV sets, radios,computers or other electric equipment.Road safety comes first! Do not use a hand-held cellular terminal or mobile whendriving a vehicle, unless it is securely mounted in a holder for hands free operation.Before making a call with a hand-held terminal or mobile, park the vehicle.GSM cellular terminals or mobiles operate over radio frequency signals and cellularnetworks and cannot be guaranteed to connect in all conditions, especially with amobile fee or an invalid SIM card. While you are in this condition and need emergenthelp, please remember to use emergency calls. In order to make or receive calls, thecellular terminal or mobile must be switched on and in a service area with adequatecellular signal strength.Some networks do not allow for emergency call if certain network services or phonefeatures are in use (e.g. lock functions, fixed dialing etc.). You may have todeactivate those features before you can make an emergency call.Also, some networks require that a valid SIM card be properly inserted in the cellularterminal or mobile.
