Refer to IR vs IO characteristics. Application Circuit 2 5 2003-08-12 TA7262P/P(LB)/F 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.
