Datasheet Charge protection ICs with Built-in FET Negative Voltage Protection type BD6047AGUL General Description Key Specifications BD6047AGUL protects the devices from the abnormal Input voltage range: 2.2V to 28V input voltage at the USB port. Voltage Protection range: 30V Addition to the conventinal charge protection IC, it Internal Low Ron: 125m(Typ.) prevents the negative voltage happened by Start Up Delay: 6.0msec(Typ.) the USB reverse insertion without any additional Operating temperature range: -40 to +85 compornents. ROHM s original charge protection IC series enables to protect the abnormal input voltage Package W(Typ.) D(Typ.) H (Max.) from -30V to +30V. Features Over Voltage Protection up to 30V Negative Voltage Protection down to -30V Over voltage Lockout (OVLO) Under voltage Lockout (UVLO) Over Current Protect Thermal Shut Down Applications Mobile phones, MP3 players, Digital Still Camera, PDA, VCSP50L1 IC recorder, Electronic Dictionary, Handheld Game, 1.95mm x 1.95mm x 0.55mm Game Controller, Camcorder, Bluetooth Headsets, etc Typical Application Circuit OVP FLGB IN CPU Cin 28V-OVP Travel 1.0uF Adapter GND OUT Cout PMIC CHGIN 0.47uF Charger BATT Li-ion 1cell Safety is high because it detects, and it protects it for an abnormal voltage up to 30V. It contributes to the miniaturization because all external is built into.
