4The Richtek RT8973A is Micro USB Switch with OVP and I2C interface. The RT8973A
5is a USB port accessory detector and switch that is optimized to protect low
6voltage system from abnormal high input voltage (up to 28V) and supports high
7speed USB operation. Also, RT8973A support 'auto-configuration' mode.
