Qualcomm Technologies, Inc. SMB5 Charger Specific Bindings



SMB5 Charger is an efficient programmable battery charger capable of charging a

high-capacity lithium-ion battery over micro-USB or USB Type-C ultrafast with

Quick Charge 2.0, Quick Charge 3.0, and USB Power Delivery support. Wireless

charging features full A4WP Rezence 1.2, WPC 1.2, and PMA support.
