RT8973AWSC Product Details

The RT8973AWSC is a USB port accessory detector and switch that is optimized to protect low voltage system from abnormal high input voltage (up to 28V). The RT8973AWSC supports high speed USB operation and I2C interface control. The RT8973AWSC provides a device detection function by using the USB ID pin signal and the VBUS voltage. The ID pin resistance and VBUS voltage determine the unique characteristics for variety accessories. The host microprocessor can use I2C interface to control the switch position and read the results of the accessory detection. The RT8973AWSC also detects USB chargers including dedicated chargers (D+/D- shorted) and high power host/hub chargers.
