CPS8843
Application
Power adapters
Car charger
Power dongles, etc.
CPS8843 is a highly integrated fast charge protocol source controller that supports charging protocols:
- BC1.2 DCP
- QC2.0/QC3.0
- SCP A and B Class
- UFCS
- PD3.1 with PPS
CPS8843 integrates constant-voltage loop (CV) and High side constant-current loop (CC) with programmable reference voltage to meet the UFCS and USB PD PPS specification.
