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).

1

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.

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-lead 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.
