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.
