1 Channel High Side Switch ICs
2.4A Current Limit High Side Switch ICs
BD82061FVJ-LB
General Description
This is the product guarantees long time support in
Industrial market.
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.
