1ch High Side Switch ICs
1.5A Current Limit High Side Switch ICs
BD2061AFJ BD2065AFJ
General Description
BD2061AFJ and BD2065AFJ are single channel high
side switch ICs with over-current protection for
Universal Serial Bus (USB) power supply line. These
ICs have low ON-Resistance N-Channel power
MOSFETs with low supply current, built-in over-current
protection circuit, thermal shutdown circuit, under
voltage lockout and soft-start circuit.
