... FROM 29319.43I Dual Full-Bridge PWM Motor Driver Description 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 drop (less than 1 ...

... L6219DS PWM Current Control The L6219DS dual bridge is designed to drive both windings of a bipolar stepper motor. Output current is sensed and controlled independently in each bridge by an external sense resistor (R internal comparator, and monostable multivibrator. When the bridge is turned on, current increases in the motor ...

... The output drivers are re-enabled when the junction temperature cools to 145°C. The L6219DS output drivers are optimized for low output saturation voltages—less than 1.8 V total (source plus sink) at 500 mA. Under normal operating conditions, when combined ...

... L6219DS Current Sensing To minimize current sensing inaccuracies caused by ground trace IR drops, each current-sensing resistor should have a separate return to the ground terminal of the device. For low-value sense resistors, the IR drops in the PCB can be signifi cant and should be taken into account. The use of sockets should be avoided as their ...
