SDC280
General Description
Features
SDC280 is a CMOS integrated circuit which includes Hall
Tsensor and output drive circuits. It’s widely used in
various small two-phase fans and DC motors. The locked
Nprotection and auto-restart function is integrated inside
Ethe IC. Input offset voltage can be dynamically adjusted by
built-in chopper amplifier, greatly improving the magnetic
Mfield sensitivity. It is built-in power reverse protection
L DOCUfunction.
