DUAL FULL-BRIDGE
PWM MOTOR DRIVER
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 deter-
mined 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.
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.
The L6219DS is supplied in a 24-pin surface-mountable SOIC. Its
batwing construction provides for maximum package power dissipation
in the smallest possible construction. This device is also available on
special order for operation from -40°C to +85°C or to +105°C. A lead-
free version (100% matte tin leadframe) is also available.

*Pb-based variants are being phased out of the product line. The variants cited in this
footnote are in production but have been determined to be LAST TIME BUY. This
classification indicates that sale of this device is currently restricted to existing
customer applications. The variants should not be purchased for new design
applications because obsolescence in the near future is probable. Samples are no
longer available. Status change: October 31, 2006. Deadline for receipt fo LAST TIME
BUY orders: April 27, 2007. These variants include:L6219DS and
L6219DSTR.
