Li ion cell charging and protection circuit for STM32WLE5JC

[David_]

(mildly off topic) To power the STM32WL5EJC, we need to make a custom board incorporating the charging and protection circuit since 30mAh Li ion cell does not have build-in protection board. 

Appreciate circuit diagram, for or similar to, the popular Li ion cell charging board using TP4056 and protection chip DW01A.  Many thanks
