1 Channel Compact High Side Switch ICs
0.3A Current Limit High Side Switch ICs
BD22621G-M
General Description
BD22621G-M is a low on-resistance N-channel
MOSFET high-side power switch, optimized for
Universal Serial Bus (USB) applications. BD22621G-M
is equipped with the function of over-current detection,
thermal shutdown, under-voltage lockout and soft-start.
