We need to build a PCBA for power bank with the following minimum characteristics:2.4A Continuous Output Current in Boost Mode2.4A Switching Charger CurrentBattery Disconnection at Output ShortBoost Auto Turn-off at No LoadBattery Over Current, Over Voltage, Over Temperature and Short Circuit ProtectionsBoost Auto Startup with Load DetectionPrioritized Power Path from Input to Output5V+/-100mV Output Voltage in Boost ModeBattery Impedance CompensationFull Cycle of Battery Charge Management Preconditioning,Fast Charge, Top off and End of ChargeCharge Current Foldback at 110°C Die TemperatureIC Over Temperature ProtectionIt have to provides a direct power path from input to output while providing power to switching charger. Output has higher priority than battery charger if the input current limit is reached battery 3100 mAH 18650USB in Type C femaleUSB out Type C male via cableMost popular smartphone compatiliby We need a custom pcb layout, attached you find the STEP file of the PCB to be.We need to receive the first samples for testing in Italy by the end of October.We have to complete a first production of 5000 pieces by the end of November.
