The goal of this project will be to update a design of a PCBA for a 2500 mAh LiPo single battery power bank. PCBA specifications: Hi, we have not found a part number of the main IC. We are now choosing a provider to update this design to a new IC. We'd like the resulting design: - to reuse as much as possible from the existing design - to fully comply with this list of requirements: 1. Input: DC5V 1A, so that battery charges at 1Amp rate 2. Outputs: two independent outputs, DC5V 1A. Connection of an external device to one output automatically blocks the other output. 3. Built-in protections for input and outputs: 3.1. overvoltage 3.2. overcurrent 3.3. short circuit 4. Built-in protections for battery: 4.1. Overcharge 4.2. Overdischarge 4.3. Overcurrent 4.4. Overheating 5. Battery charging/discharging: standard 3.7V LiPo battery charging cycle, 2500 mAh battery (we will provide the samples) 6. Simple shake sensor: activates LED indication. Example:   [obscured]  /Electron...
