Smart Machine Smart Decision 3 Application Interface Specification 3.1 Power Supply The power supply pins of SIM5320ALD 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 current consumption rises typically to peak of more than 2A. So the power supply must be able to provide sufficient current up to more than 2A. The following figure is the VBAT_RF voltage ripple wave at the maximum power transmit phase.
Smart Machine Smart Decision beside VBAT_RF pins as close as possible. Also User should minimize the PCB trace impedance from the power supply to the VBAT pins through widening the trace to 80 mil or more on the board. The following figure is the recommended circuit. Figure 8: VBAT input application circuit There are three sections about how to design and optimize users’ power systems.
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”.
