20 uA 3.1.1 Power supply Design Guide Make 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 220uF capacitors is recommended, or else users must use a total of 1000uF capacitors, in order to avoid the voltage drop of more than 300mV. Some multi-layer ceramic chip (MLCC) capacitors (0.1/1uF) with low ESR in high frequency band can be used for EMC. These capacitors should be put as close as possible to VBAT pads. Also, user should keep VBAT trace on the circuit board wider than 2 mm to minimize PCB trace impedance. The following figure shows the recommended circuit. Figure 5: Power supply application circuit SIM7600A_User Manual_V1.01 2017-10-10 20 Smart Machine Smart Decision In addition, in order to guard over voltage protection, it is suggested to use a zener diode with 5.1V reverse zener voltage and more than 500mW power dissipation.

SIM7600A_User Manual_V1.01 2017-10-10 26 Smart Machine Smart Decision 3.3.2 RI and DTR Behavior The RI pin can be used to interrupt output signal to inform the host controller such as application CPU. Normally RI will stay at high level until certain conditions such as receiving SMS, or a URC report come in. It will then change to low level. It will stay low until the host controller clears the interrupted event with AT+CRIRS AT command. Figure 15: RI behaviourSMS and URC report Normally RI will be kept high until a voice call, then it will output periodic rectangular wave with 5900ms low level and 100ms high level. It will output this kind of periodic rectangular wave until the call is answered or hung up.

In this mode, the RF part of the module will not work but the serial port and USB port are still accessible. The power consumption in this mode is lower than normal mode. Module will go into power off mode by sending the AT command AT+CPOF or by pulling down the PWRKEY pin normally. In this mode the power management unit shuts down the power supply and software is not active. The serial port and USB are is not accessible. Power off 5.3.2 Sleep Mode In sleep mode, the current consumption of module will be reduced to the minimal level, and module can still receive paging message and SMS. Several hardware and software conditions must be satisfied together in order to let Module enter into sleep mode:

1. UART condition 2. USB condition 3. Software condition Note: Before designing, pay attention to how to realize sleeping/waking function and refer to Document [26] for more details. 5.3.3 Minimum Functionality Mode and Flight Mode Minimum functionality mode ceasesa majority functionof module, thus minimizing the power consumption. This mode is set by the AT command which provides a choice of the functionality levels. AT+CFUN=0: Minimum functionality AT+CFUN=1: Full functionality (Default) AT+CFUN=4: Flight mode If Module has been set to minimum functionality mode, the RF function and USIM card function will be closed. In this case, the serial port and USB are still accessible, but RF function and USIM card will be unavailable. If Module has been set to flight mode, the RF function will be closed. In this case, the serial port and USB are still accessible, but RF function will be unavailable. When Module is in minimum functionality or flight mode, it can return to full functionality by the AT command AT+CFUN=1. 5.4 Current Consumption The current consumption is listed in the table below.

Safety Caution Table 42: Safety caution Marks Requirements When in a hospital or other health care facility, observe the restrictions about the use of mobiles. Switch the cellular terminal or mobile off, medical equipment may be sensitive and not operate normally due to RF energy interference. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched off. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. Forgeting to think much of these instructions 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 or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard. Your cellular terminal or mobile receives and transmits radio frequency energy while switched 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 when driving 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 cellular networks and cannot be guaranteed to connect in all conditions, especially with a mobile fee or an invalid SIM card. While you are in this condition and need emergent help, please remember to use emergency calls. In order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Some networks do not allow for emergency call if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may have to deactivate those features before you can make an emergency call. Also, some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile.
