The RH7902A is an ultra low power, 8-pin USB interface IC manufactured by RONGHE. It is built using advanced CMOS process technology and packaged in a SOT-23-6 form factor (RoHS compliant). The RH7902A is designed for use in consumer electronic devices and provides a high speed link between the host and a USB peripheral device. It supports both high speed (480 Mbps) and full speed (12 Mbps) USB connections. The device features 1.4V to 3.6V power supply voltage range, 0 to 44 MHz clock frequency, 8-bit MCU interface, switching power supply up to 100mA current, and USB 2.0 On-The-Go (OTG) compatible. The IC is capable of handling multiple types of data protocols and provides all the necessary signal level conversion, as well as voltage level translation for an effective, low-power USB interface.
