High Side Switch ICs

BD2244G-M BD2245G-M

General Description

Key Specifications

BD2244G-M and BD2245G-M are low on-resistance

N-channel MOSFET high-side power switches,

optimized for Universal Serial Bus (USB) applications.

BD2244G-M and BD2245G-M are equipped with the

function of over-current detection, thermal shutdown,

under-voltage lockout and soft-start. Moreover, the range

of Current limit threshold can be adjusted from 0.2A to

1.7A by changing the external resistance


