SIM7075G User Manual V1.00 3. Interface Application 3.1 Power Supply Pin 32, pin 33 and pin 52, pin 53 are VBAT power input. On VBAT pads, when module works on CAT-M1 mode, the ripple current is up to 0.6A typically. For steady voltage, the power supply capability must be up to 0.5A. On VBAT pads, when module works on EDGE or GPRS mode, The ripple current is up to 2A typically. For steady voltage, the power supply capability must be up to 2A.
SIM7075G User Manual V1.00 3.1.1 Power Supply Design Guide In the user's design, special attention must be paid to the design of the power supply section to ensure that the VBAT drop cannot be lower than the minimum voltage shown in Table 7 even when the module current consumption reaches the instantaneous maximum. If the VBAT voltage drops below the minimum input voltage, the module may shut down due to low voltage. Table 7: Minimum input voltage Module Minimum input voltage(V) SIM7075G 3.
SIM7075G User Manual V1.00 3.1.2 Recommended Power Supply Circuit If the supply voltage exceeds the supply range of VBAT, the buck circuit should be used to meet the demand of power supply. When choosing buck chip, besides considering the maximum current output capability of IC to meet the demand of SIM7075G, it is also necessary to consider the low static power consumption of IC in PSM mode. Figure 7: Power supply reference circuit 3.1.
SIM7075G User Manual V1.00 3.2.1 Power on The PWTRKEY pin has a default voltage of 1.5V. SIM7075G can be powered on by briefly pulling the PWRKEY pin to ground. It is strongly recommended to put an ESD protection diode close to the PWRKEY pin, as it would strongly enhance the ESD performance of PWRKEY pin. The PWRKEY pin has its own reset function. The reset time is determined by the internal timer (default is 12.6 seconds). After the PWRKEY is pulled low, the module will be reset after 12.6 seconds.
