Negative Voltage Protection Type - BD6046GUL

BD6046GUL protects the devices from the abnormal input voltage at the USB port.
Addition to the conventinal charge protection IC, it prevents the negative voltage happened by the USB reverseinsertion without any additional compornents.
ROHM's original charge protection IC series enables to protect the abnormal input voltage from -30V to +30V.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
