Unisonic Technologies L6219
The L6219 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 45V and include internal pulse-width modulation (PWM) control of the output current to 750mA .The outputs have been optimized for a low output saturation voltage drop (less than 1.8V total source plus sink at 500mA ). For PWM current control, the maximum output current is determined by the user’s selection of a reference voltage and sensing resistor.| Part No. | L6219 |

DESCRIPTION
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. The bridges include both ground clamp and flyback diodes for protection against inductive transients. Internally generated delays prevent cross-over currents when switching current direction. Special power-up sequencing is not required. Thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits.●
