Power Management Switch ICs for PCs and Digital Consumer Products

1ch High Side Switch ICs

for USB Devices and Memory Cards

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.
