New 2C1A three-port USB PD controller with flexible miniaturization for 18W~65W multi-port fast charging design

In response to the trend of multi-port fast charging in the fast charging source market, Hynetek is introducing a high-performance, highly integrated USB Type-C*2 and USB Type-A*1 3-port PD controller, HUSB390, for fast implementation of multi-port fast charging designs such as 2C and 2C1A with 18 W~65 W.

In addition, the HUSB390 integrates all necessary protections such as OVP, UVP, UVLO, OCP, FOCP, CC or DPDM OVP, and TSD. The HUSB390 is packaged in a QFN-40L (5 mm x 5 mm) package and is suitable for a variety of multi-port power adapters, car chargers, plugs, etc.

VIN1 connected to VIN2

When a single port is connected, USB PD or HVDCP is enabled; when two or three ports are connected simultaneously, only 5V output is available.

VIN1 not connected to VIN2

When single port is connected, USB PD or HVDCP is enabled; if 1A1C is connected at the same time, both ports share 5 V; if 3 ports are plugged together, 1A1C of them share 5 V and the other C port still supports fast charging.

In addition, the HUSB390 automatically recognizes the presence or absence of cables on the port for a better fast charging experience.

1C port

• Support fast charging, PD output voltage and current free setting

• DPDM supports 5V2.4A, DCP, QC, FCP, AFC, SCP, PE and other protocols

• Support constant voltage and constant current control

1A port

• DPDM supports 5V2.4A, DCP, QC, AFC, FCP, PE and other protocols

• 18 W default output, programmable

• Supports insertion and removal detection (5 mA)

Any two ports and above

• Same plug return 5 V, total output current constant current control, size programmable

In the face of the current market more small and medium power multi-port fast charging needs, the above design can perfectly realize the single chip control three ports fast charging needs, greatly reducing the design difficulty and reduce the BOM cost. In addition, HUSB390 can judge the threshold at low light load, which can solve the problem of filling up small current devices.

1C port

• PD output voltage and current free setting, maximum support 65 W fast charging

• DPDM supports 5V2.4A, DCP, QC, FCP, AFC, SCP, PE and other protocols

• Support constant voltage and constant current control

1A port

• DPDM supports 5V2.4A, DCP, QC, AFC, FCP, PE and other protocols

• 18 W default output, programmable

• Support plug-in and pull-out detection (5mA)

Dual-port co-location

• When 2 C ports are plugged together, or C1 and A2 are plugged together, both ports support fast charging, intelligent power allocation, programmable

• When C2 and A2 are plugged together, shared 5 V charging

3 ports plugged together

• C1 supports fast charging, output voltage and current can be set freely; C2 and A2 share 5 V

The above intelligent power-down design allows flexible multi-port fast charging design from 35 W to 65 W medium-high power. Meanwhile, the fast charging power can be freely set according to the demand, which can improve the charging efficiency.
