Minimalist periphery, cost-effective

The HUSB382E integrates two N-MOSFETs and two sampling resistors in an ESOP-8L package, requiring only one external component to greatly simplify the design. This highly integrated, minimalist peripheral design maximizes savings in SMT and BOM costs. Whether for engineers pursuing ultimate cost efficiency or brands aiming for rapid market deployment, the HUSB382E delivers an economical and hassle-free ideal solution.

Supports light-load detection

Both port C and port A of HUSB382E support light load detection function, which can solve the problem that port C only accesses the Apple cable (no cell phone) and port A has no fast charging.

More Comprehensive Functionality

HUSB382E is equipped with current sampling function, capable of accurate OCP (overcurrent protection) and two-port mode accurate current limiting, ACDC can be realized without the need of constant power solution. Due to the current sampling function, it is able to give out the line supplement, and the line supplement has multiple levels to choose from.

Supports multiple protocols

Protocol support, the C port supports the PD protocol, but also supports the 3-meter cable and device charging; support for Samsung cell phone display ultra-fast charging and ultra-fast charging 2.0. the A port on the basis of which also supports the BC1.2 DCP and HVDCP protocols, including QC3.0+ and PE2.0.
