Power Management Switch IC Series for PCs and Digital Consumer Product
1ch Large Current Output
USB High Side Switch ICs
BD2061AFJ,BD2065AFJ
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 80mΩ Nch MOSFET Switch.
2) Continuous current load 1.0A
3) Control input logic
Active-Low : BD2061AFJ
Active-High : BD2065AFJ
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 power switch off
10) Power supply voltage range 2.7V~5.5V
11) TTL Enable input
12) 1.2ms typical rise time
13) 10μA max standby current
14) Operating temperature range -40°C~85°C
Applications
USB hub in consumer appliances, Car accessory, PC, PC peripheral equipment, and so forth
