The HUSB305 is a USB Type-C Source port controller, which integrates multiples essential functions for a USB Type-C port. There is an ultra-low Rdson (15mΩ) N-channel MOSFET integrated. It is designed for a 5V USB Type-C 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. The 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 the HUSB305 so that it can performs an OVP, OCP, OTP. The HUSB305 has Type-C 1.5A/ 3A protocols integrated. It can automatically switch different Rp per the ISET setting.Only 120μA operation current is required for the HUSB305 to save the standby power loss of whole system.
