BD2061AFJ BD2065AFJ
●General Description
Single channel high side switch IC for USB port is a high side switch having over current protection used i n 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
Low on resistance 80mΩ N-ch MOSFET Switch. Continuous current load 1.0A Control input logic
¾ Active-Low : BD2061AFJ
¾ Active-High: BD2065AFJ Soft start circuit Over current detection Thermal shutdown Under voltage lockout Open drain error flag output Reverse-current protection when power switch off TTL Enable input 1.2ms typical rise time
●Applications
USB hub in consumer appliances, Car accessory, PC, PC peripheral equipment, and so forth
