USB Charge Conditioner – IC-USBCC

Functions:

– USB VBus Conditioning: Opens the VBus connection in case VBus is below the 4.5 USB-specified minimum.
– USB VBus Overvoltage Protection: Opens the VBus connection in case VBus is above 6V.- USB VBus Reverse Voltage Protection: Opens the VBus connection in case VBus is negative.- USB Signaling Pair Transient Suppression: Clamps USB pair transients to ground.Applications: – USB Charge Conditioner may be very useful in any circumstance where an RT-series instrument is connected to a questionable USB charger, including home-made USB charge sources. It will protect the instrument against VBus over-voltage as well as reverse-voltage.- USB Charge Conditioner may be very useful in circumstances where the instrument is charged over a long stretch of USB cable, especially outdoors. It will protect the USB pair against high-voltage transients.
