USB TYPE-C/PD controller with integrated VBUS-to-CC short circuit protection

The invention relates to a USB TYPE-C/PD controller with integrated VBUS to CC short circuit protection. A USB Type-C/power transfer controller chip (200) comprises: a first pin (201) for receiving a first voltage (PP CABLE); a second pin (203) for receiving a second voltage (LDQ 3V3); and a third pin (205) for coupling to a CC pin of a USB connector (212). The controller chip (200) includes a VCONN power circuit (206) having a blocking field effect transistor (BFET) (MN1) coupled in series with a hot plug field FET (HSFET) (MN2) between the first and third pins (201, 205), and first and second Zener diodes (D1, D2) coupled anode to anode between a source and a gate of the HSFET. A cable detection circuit (202) includes a BFET (MN3) coupled between the second and third pins (203, 205), and a Zener diode (D3) coupled between a gate of the BFET and a lower rail. 本申请涉及一种具有集成VBUS到CC短路保护的USB TYPE-C/PD控制器。一种USB Type-C/电力输送控制器芯片(200)包含：第一引脚(201)，其用于接收第一电压(PP CABLE)；第二引脚(203)，其用于接收第二电压(LDQ 3V3)；及第三引脚(205)，其用于耦合到USB连接
