ROHM BD82001FVJ Technical data

Power Management Switch ICs for PCs and Digital Consumer Products
1ch High Side Switch ICs for USB Devices and Memory Cards
●Description
Single channel high side switch IC for USB port is a high side switch having over-current protection used in power supply line of universal serial bus (USB). N-channel power MOSFET of low on resistance and low supply current are realized in this IC. And, over-current detection circuit, thermal shutdown circuit, under-voltage lockout and soft start circuit are built in.
●Features
1) Low On-Resistance 70mΩ MOSFET Switch
2) Current limit threshold 1.5A
3) Control Input Logic Active “Low” Control Logic : BD82000FVJ Active “High” Control Logic : BD82001FVJ
4) Soft-Start Circuit
5) Over-Current Protection
6) Thermal Shutdown
7) Under-Voltage Lockout
8) Open-Drain Error Flag Output
9) Power Supply Voltage Range 2.7V~5.5V
10) TTL Enable Input
11) 0.8ms Typical Rise Time
12) 1μA Max Standby Current
●Applications
PC, PC peripheral equipment, USB hub in consumer appliances, Car accessory, and so forth
