ROHM BD6046GUL Technical data
Charge Protection IC Series with Built-in FET
Negative Voltage
Protection type
BD6046GUL
●Descriptions
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 reverse
insertion without any additional compornents.
ROHM's original charge protection IC series enables to protect the abnormal input voltage from -30V to +30V.
●Features
1) Overvoltage Protection up to 28V
2) Negative Voltage Protection
3) Internal Low Ron (250mΩ) FET
4) Over voltage Lockout (OVLO)
5) Under voltage Lockout(UVLO)
6) Internal 2.5msec Startup Delay
7) Over Current Protect
8) Thermal Shut Down
9) Small package: VCSP50L2(2.5mm x 2.5mm, height=0.55mm)
●Applications
Mobile phones, MP3 players, Digital Still Camera, PDA, IC recorder, Electronic Dictionary, Handheld Game, Game
Controller, Camcorder, Bluetooth Headsets, etc
●Absolute maximum ratings (Ta=25℃)
