Power Management Switch ICs for PCs and Digital Consumer Products

1ch High Side Switch ICs

for USB Devices and Memory Cards

No.11029EBT03

BD2041AFJ,BD2051AFJ,BD6519FJ

●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) Built-in low on resistance Nch MOS FET Switch.

Typ = 80mΩ (BD2041AF/BD2051AFJ)

Typ = 100mΩ (BD6519FJ)

2) Continuous current load 0.5A

3) Control input logic

Active-Low : BD2041AFJ/ BD6519FJ

Active-High : BD2051AFJ

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 (BD2041AF/BD2051AFJ)

3.0V~5.5V (BD6519FJ)

11) Operating temperature range -40°C~85°C

●Applications

USB hub in consumer appliances, Car accessory, PC, PC peripheral equipment, and so forth
