Application Circuit 3
Q2 works as a Current Regulator for Output Coil. Therefore, Collector to Emitter Voltage of Q2 is varied in
accordance with required coil current.
Note 1: Utmost care is necessary in the design of the output line, VS and GND line since IC may be destroyed due to
short−circuit between outputs, to supply, or to ground.
Note 2: Don’t keep 3 ST terminal open.
Note 3: Voltage of the position sensing input: 20mVPP to 400mVPP.
(Hb and Hc waveforms operate similar to Ha)
