USB-IF certified minimalist PD fast charging solution HUSB352B

5 30, 2025

The HUSB352B is a high performance, high integration USB Type-C and PD controller. It integrates the VBUS power switch and current sensing resistor to save board space and BOM cost.The HUSB352B is a USB PD3.1 controller which supports 3 FPDOs and 2 APDOs with programmable current and voltage. Additionally, it is compatible with a range of charging protocols, including BC1.2 DCP, Apple 5V 2.4 A, QC2.0/3.0/QC3+, AFC, FCP, and SCP, as well as PE1.1+/2.0.The HUSB352B integrates all required protections, including Over voltage Protection (OVP), Under voltageProtection (UVP), Under voltage Lockout (UVLO), Overcurrent Protection (OCP), Fast Overcurrent Protection (FOCP), and Thermal Shut Down (TSD).It is available in SOP-8L package.

More streamlined periphery

The HUSB352B has a built-in N-MOSFET and a sampling resistor that supports constant current, so only one peripheral device is needed to complete the entire circuit design in practical applications. The highly integrated design effectively reduces the patch cost and material cost. It allows engineers to focus more on the development of the product's core functions rather than on the design of cumbersome peripheral circuits.

More Comprehensive Functionality

HUSB352B is equipped with a current sampling function that enables accurate OCP (overcurrent protection), effectively preventing devices from being damaged due to excessive current during the charging process. Secondly, it also supports PPS constant current function, which can dynamically adjust the output voltage and current according to the charging demand of different devices, and realize stable charging effect even in ACDC without constant power solution. In addition, due to the current sampling function, it is able to give a line supplement, which is equipped with a number of gears to choose from, so that the user can adjust it flexibly according to the actual needs, further optimizing the charging experience.

Wider compatibility

In terms of protocol support, the HUSB352B not only supports the USB PD protocol, but also the PE1.1+/2.0 protocol, further expanding compatibility.The HUSB352B is able to support a 3-meter cable to charge with devices. For Samsung cell phone users, the HUSB352B also displays the status of Ultra Fast Charging and Ultra Fast Charging 2.0, providing users with an intuitive and efficient charging experience.
