BENDRAS APRAŠYMAS

The HUSB238 is a highly integrated USB Power Delivery (PD) controller as sink role. The HUSB238 is compatible with USB PD3.0 V1.3 and Type-C V1.4. And it can also support charge protocols such as Apple divider 3, BC1.2 SDP, CDP and DCP. The HUSB238 can be used in electronic devices that have legacy barrel connectors (called Barrel Connector Replacement) or USB micro-B connectors. The applications can be wireless chargers, IoT (Internet of Things) devices, drones, smart speakers, power tools, and other rechargeable devices. The HUSB238 is available in 3 mm x 3 mm DFN-10L package and 3.9mm x 4 mm SOT33-6L package.

NOTES FOR THE EVALUATION DESIGN BOARD
The RDO of HUSB238 default factory setting is 20V3.25A. If the USB Type-C cable does not have an eMarker chip or the eMarker indicates the cable current rating being only 3A, the maximum current rating of source capability of the PD power adapter is only 3A and the PD power adapter will fail to match the HUSB238. In this situation, the request current can be set to 3A (or smaller) by changing the external resistor RISET to 22kΩ (or smaller).

VOLTAGE AND CURRENT REQUEST PRINCIPLE 

  • HUSB238 supports three kinds of voltage and current request methods:
    • Factory defaults settings (Default request voltage and current is 20V3.25A, custom design is also allowed).
    • VSET & ISET pins dynamic setting of the targeted voltage and current by changing of the RVSET and/or RISET resistors connected to the VSET & ISET pins separately.
    • I 2 C advanced setting.
  • Ttage and current of HUSB238 actually request is the lower of factory defaults setting and the VSET/ISET pins setting.
    • Dėl example, if factory default request voltage is 20V, the VSET pin request voltage is 12V, the actual request voltage yra 12V.
    • Dėl example, if factory default request current is 2A, the ISET pin request current is 3A, and the actual request current is 2A.
  • I 2 C advanced setting has the highest priority, it can bypass the above two kinds of settings:
    • HUSB238 stores source capability received from the USB PD power adapter. It includes all FPDOs data and other information sent from the USB PD power adapter. The MCU can choose the proper PDO according to this information.
    • It is suggested the VEST pin be shorted to ground such that the default request voltage 5V. Then the MCU request the actual required voltage & current through the I2 C interface.
  • Matching mechanism.
    • Tik ttage and current of the PD source meet the both conditions, it can be matched.
      • Prašymas ttage value must less-than or equal-to Source PDO voltage verte.
      • Request current value must less-than or equal-to Source PDO current value.
    • If the conditions are not matched, according to the HUSB238 mismatch rules, you can choose:
      • Look down for a lower voltage for matching. For example, HUSB238 requests 60W 20V3A, but the PD source provides 45W with PDOs of 5V3A, 9V3A, 12V3A, 15V3A and 20V2.25A. The 20V2.25A PDO fails to match, while the 15V3A PDO matches.
      • Request 5V PDO directly.
