Noise generated by the motor can be reduced by linear driving system. Forward/reverse rotation can be switched. This IC has current limit circuit and FG output. 1) Linear driving system 2) Forward/reverse select switch 3) Built-in current limiter and thermal shut down 4) FG output
*If VM voltage is low, this IC may not be able to flow the output current by absolute maximum ratings. mA mV Application Circuit Operating supply voltage range VCC —5 17 V Operating supply voltage range VM —3.5 17 V Hall Amp in-phase voltage range VCH —1.1 VCC–1.0 V V V V V V Recommended Operating Conditions (Ta=25˚C) Parameter Min.
