Smart Machine Smart Decision 2.4 Footprint Recommendation Figure 6: Footprint recommendation (Unit: mm) 3 Application Interface Specification 3.1 Power Supply The power supply pins of SIM5320AD include VBAT_RF and VBAT_BB. VBAT_RF directly supplies the power to RF PA; VBAT_BB supplies the power to the baseband system. For the VBAT_RF, the ripple due to GSM/GPRS emission burst (every 4.615ms）may cause voltage drop, and the current consumption rises typically to peak of 2A.

Smart Machine Smart Decision Figure 8: VBAT input application circuit There are three sections about how to design and optimize users’ power systems. Power supply circuit We recommend DCDC or LDO is used for the power supply of the module, make sure that the peak current of power components can rise up to 2A. The following figure is the reference design of +5V input power supply. The designed output for the power supply is 4.1V, here a linear regulator can be used.

Smart Machine Smart Decision Figure 10: Reference circuit of the DCDC power supply Voltage monitor To monitor the power supply voltage, user can use the AT command “AT+CBC”, this command has two parameters: the battery status and the voltage value (mV). It will return the capacity percentage and actual value of battery (at the VBAT_BB pin). The voltage is continuously measured at intervals, whenever the measured battery voltage is lower than a specific value set by the AT command “AT+CVALARM”.

Smart Machine Smart Decision components can only be obtained after the antenna tuning usually, and they are provided by antenna vendor.C2 in Figure 27 is used for DC isolation. In active antenna circuit, users must use an external LDO/DCDC to provide VDD voltage whose value should be taken according active antenna characteristic, and VDD can be shut down to avoid consuming additional current when not being used. GPS can be used by NMEA port. User can select NMEA as output through UART or USB.

In this mode, SIM5320AD can still receive paging，voice call or SMS from network. If USB interface of SIM5320AD is connected to host CPU, but host CPU does not support USB suspending, then SIM5320AD will not enter sleep mode. After USB is disconnected, SIM5320AD will enter sleep mode.
