SDC280

Smart Two-Phase DC Fan Datasheet 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.  High voltage CMOS technology  Peak output current up to 1A  Operating voltage range:3.5V~24V  Sustainable 350mA operating current  High sensitivity Hall sensor  Locked protection and auto-restart  Power reverse protection  Including protection diodes to clamp the output  Operating temperature: -40°C~85°C  Package: TO-94 Applications  Brushless DC fan motors  Brushless DC motors CONFIDENTIATO-94 SDC Figure 1.
