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 1.8 V total source
plus sink at 500 mA).
For PWM current control, the maximum output current is
determined by user 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.
The bridges include both ground clamp and flyback diodes for
protection against inductive transients. Internally generated
delays prevent crossover 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.
The L6219DS is supplied in a 24-pin surface-mountable SOIC,
with 4 internally-fused leads for maximum package power
dissipation in the smallest possible construction. It is lead (Pb)
free with 100% matte tin leadframe plating.
