USB Type-C Source Controller with Power Switch Hynetek Semiconductor Co., Ltd. Features Integrated 15mΩ Power Switch Programmable Current Limit Low Load Current Sensing Integrated USB Type-C Rp Current Source Automatic USB Type-C Rp 1.5A/3A Switching Status Indication Over Voltage and Over Current Protection Low Operation Current ±8k V HBM ESD Rating for USB IO pins GENERAL DESCRIPTION HUSB305 is a USB Type-C Source port controller, which integrates multiples essential functions for a USB Type-C source port. There is an ultra-low conduction resistance (15mΩ) N-channel MOSFET integrated. It is designed for a 5V USB Type-C source port application, which requires a high current switch. The programmable current limit provides an easy way to fine-tune the current limit through an external resistor. HUSB305 can detect its load current and change its status output to notify that there is a load applied at the current USB Type-C port. The output voltage and output current are both monitored by HUSB305 so that it can performs an OVP, OCP, OTP. HUSB305 has USB Type-C 1.5A/ 3A protocols integrated. It can automatically switch different Rp per the ISET setting. Only 150μA operation current is required for HUSB305 to save the standby power loss of whole system.
