Power Management Switch ICs for PCs and Digital Consumer Products

2ch High Side Switch ICs

for USB Devices and Memory Cards

No.11029EBT05

BD2046AFJ, BD2056AFJ

●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.

●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

●Applications

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