AFC Controller HY5204S



Samsung AFC Adapter


HY5204S is a dedicate silicon implementation on AFC protocol. In the meantime, HY5204S system provides high reliability and cost-effective solution for AFC applications.

HY5204S integrates CC/CV loop compensation, cable drop compensation and control scheme inside silicon. It has OVP, UVP, OTP and D- impedance detection protections. To satisfy system power consumption requirement, HY5204S design minimizes quiescent current in order to meet standby power consumption of power adaptor.

HY5204S is available for SOT23-6 package.
