5 / 9 page The source transistors are used to switch the power supplied to the motor winding, thus driving a constant current through the winding. It should be noted however, that is not permitted to short circuit the outputs. Internal circuitry is added in order to increase the accuracy of the motor current particularly with low current levels. VS, VSS, VRef The circuit will stand any order of turn-on or turn- off the supply voltages VS and VSS. Normal dV/dt values are then assumed. Preferably, VRef should be tracking VSS during power-on and power-off if VS is established. APPLICATION INFORMATIONS (Note 1) Some stepper motors are not designed for contin- uous operation at maximum current. As the circuit drives a constant current through the motor, its temperature might increase exceedingly both at low and high speed operation. Also, some stepper motors have such high core losses that they are not suited for switch mode Figure 2: Principle Operating Sequence L6219 5/9 |
