l         Package: TO-94

l         Built-in FG output

l         Low quiescent supply current under 5mA

l         Output sink current up to 0.25A

l         Wide operating voltage range: 4.5V~20V

FEATURES

l         1-chip hall sensor/drivers

The SDC211,a 1-chip composed of hall sensor and output coil drivers, applied to 2-phase DC motor. The high sensitivity of Hall effect sensor is suitable for motors from mini-type CPU coolers to blowers and DC fans. Typical operation current is 0.25A and operating voltage range is wide. FG signal, an open collector, provides a square waveform output for the detection of the motor speed.Using few external components, SDC211, a high performance integrated IC, is designed for a 2-phase DC motor circuit. The circuit diagram of the typical application example is as below.
