Hello all,

I am intending to make a wearable device that have a GYRO, ACC sensors, monochrome display, BLE connection. the wearable will be powered with a rechargeable 50mAh (both wired and wireless charging).
I have checked multiple solutions from different semiconductor manufacturers but i didn't know which one is suitable for this kinda battery capacity!

also most solutions consist of multiple ICs (protection, fuel guage, charge, and wireless ICs).. but i would prefer a one IC solution for space management.
can anyone worked on a similar project suggest some battery management solution/power stage for wearables!? or say which of the above solutions could be a better fit for my application !?

Thank you in advance,
