BC127 Power Supply & Battery Charger


I’m building around the BC127, and I like the fact that I can throw out my LiPo charger IC, but I have some questions about how to lash up the charging circuitry, etc. The BC127 Product Technical Specification found here source.sierrawireless.com/resou … +Documents
says that if you want to be able to charge a ‘flat’ battery, you need to make sure that the VDD_PADS receives power (3.3V nom). My question is if I have 3.3V on the VDD_PADS pin, but I have the VREGEN pin pulled low (which, I understand, disables the module) will the charge circuitry work?
