1.0A Current Limit High Side Switch ICs

BD2041AFJ BD2051AFJ

General Description

Key Specifications

BD2041AFJ and BD2051AFJ 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.
