Product Descriptions

The HUSB304 is a USB port controller, which integrates common functions for a USB Type-A port. There is an ultra-low Rdson (15mΩ) N-channel MOSFET integrated. It is designed for a 5V USB Type-A 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 HUSB304 can detect its load current and change its status output to notify that there is a load applied at the current USB Type-A port. The output voltage and output current are both monitored by the HUSB304 so that it can performs an OVP, OCP, OTP. The HUSB304 has Divider 3, USB DCP applying 1.2V, BC 1.2 DCP and Chinese Telecommunication Industry Standard YD/T 1591-2009 protocols inside. It can automatically detect the attached devices and switch to the proper charging protocol. Only 70μA operation current is required for the HUSB304 to save the standby power loss of whole system.
