ï¬Description
High side switch for USB is a high side switch having over current protection used in power supply line of universal serial bus
(USB). Its switch unit has two channels of N-channel power MOSFET. And, over current detection circuit, thermal shutdown
circuit, under voltage lockout and soft start circuit are built in.
ï¬Features
1) Dual N-MOS high side switch
2) Continuous current load 0.25A
3) Control input logic
Active-Low : BD2046AFJ
Active-High : BD2056AFJ
4) Soft start circuit
5) Over current detection
6) Thermal shutdown
7) Under voltage lockout
8) Open drain error flag output
9) Reverse-current protection when switch off
10) Flag output delay filter built in
ï¬Applications
USB hub in consumer appliances, Car accessory, PC, PC peripheral equipment, and so forth
