My team and I are designing a PCB for a robotic prosthetic hand. We want to be able to plug in a USB and have the PCB charge a LiPo 7.4V 2S, 1300mAh battery pack. We would like the components of the PCB to balance the cells and protect them from over and under voltage.
Essentially, we want the cells to be well monitored and stable as they will be in the prosthetic and attached to someone. We do not require any interface with a microcontroller, although this could be nice in the future--same goes for temperature monitoring.
The battery will output directly to a voltage regulator (TPS54627) as all of our servos and sensors run on 5V. Any suggestions would be helpful, but I will try and look more into options. Just unsure of what features to include on which chip, how many we need, etc.
Thanks,
JD
