|
The Richtek RT8973A is Micro USB Switch with OVP and I2C interface. The RT8973A
|
||
|
|
is a USB port accessory detector and switch that is optimized to protect low
|
||
|
|
voltage system from abnormal high input voltage (up to 28V) and supports high
|
||
|
|
speed USB operation. Also, RT8973A support 'auto-configuration' mode.
|
||
|
|
If auto-configuration mode is enabled, RT8973A would control internal h/w patch
|
||
|
|
for USB D-/D+ switching.
