L6219

The L6219DS motor driver is designed to drive both windings of a bipolar stepper motor or bidirectionally control two dc motors. Both bridges are capable of sustaining 45 V and include internal pulse-width modulation (PWM) control of the output current to 750 mA. The outputs have been optimized for a low output saturation voltage _d_r_o_p_(less than 1.8 V total source plus sink at 500 mA).

For PWM current control, the maximum output current is determined by the user´s selection of a reference voltage and sensing resistor. Two logic-level inputs _select_output current limits of 0, 33, 67, or 100% of the maximum level. A PHASE input to each bridge determines load current direction.
