1 Channel Compact High Side Switch ICs
1.0A Current Limit High Side Switch ICs
BD2240G BD2241G
General Description
BD2240G and BD2241G are low ON-Resistance
high-side power switches N-Channel MOSFETs for
Universal Serial Bus (USB) applications. These ICs
have built-in over-current protection, thermal shutdown,
under-voltage lockout and soft-start.
