3.2A Current Limit High Side Switch ICs
BD82046FVJ
Description
BD82046FVJ is a Single Channel High Side Switch IC
employing N-channel power MOSFET with low on
resistance and low supply current for the power supply
line of universal serial bus (USB).
This IC has a built-in over current detection circuit,
thermal shutdown circuit, under voltage lockout and
soft start circuits.
