Smart Two-Phase DC Fan

SDC280

General Description

SDC280 is a CMOS integrated circuit which includes Hall

sensor and output drive circuits. It’s widely used in

various small two-phase fans and DC motors. The locked

protection and auto-restart function is integrated inside

the IC. Input offset voltage can be dynamically adjusted by

built-in chopper amplifier, greatly improving the magnetic

field sensitivity. It is built-in power reverse protection

function.
