It is necessary to ensure that the voltage of VABT cannot be lower than 3.3V after the maximum voltage drop. the module will be powered off automatically. The max voltage is not higher than 4.4V, otherwise the module may be permanently damaged.
SIM8260A_Hardware Design_V1.05 This chapter is under development. The indicated peak power consumption data is an estimated value, not the final measured data. The data will be supplemented by subsequent versions. Figure 4: Power consumption at ENDC combination of B2 (20MHz) and N79 (100MHz) NOTE Test conditions The total capacitors of VBAT net are not less than 640uF.
SIM8260A_Hardware Design_V1.05 Test conditions The above current consumption data is measured using SIMCOM EVB. The test current consumption data includes SIM8260A module, SIMCom WLAN module W82 and Ethernet PHY RTL8125B, to be added in subsequent versions.
