SDC266

Switch Hall IC Datasheet SDC266 General Description The SDC266 is an integrated circuit which includes Hall sensor and output drive circuits. It’s widely used in 2-phase brushless DC motor and fan. It’s composed of power reverse protection circuit, high stable voltage regulator, Hall voltage generator, a differential amplifier, Schmitt trigger and open collector output (DO, DOB). In the case of power supply reverse connecting, the internal protection diode can protect IC but not protect coil, a protection diode can be added if necessary. Features  Wide operating voltage range: 3.5V~24V  250mA(AVG) output sink current  Building-in protection diode  Operating temperature range: -20°C~85°C  Package: TO-94 Applications  Brushless DC motor  Brushless DC fan  Revolution counting  Speed measurement TO-94 Figure 1.
