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, air contamination fault, or fault by improper grounding.
Note 2: Don't keep 3 ST terminal open.
