I have been working a project where I am using an esp32-S3 for a wearable. It will run off a 3.7V LiPo battery. For the charging circuit I copied the following off a dev board:
at the top is the usb interface, in the middle is the charging circuit with the voltage divider for reading the battery voltage, and the bottom is the LDO voltage regulator supplying the +3.3V to the rest of the circuit.
I recently can across the LTC4063
This chip seems to be able to combine both the charging and voltage regulation in one chip. Anyone have experience with using this chip?
Thanks!
