Description
The UDx2916 motor drivers 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.Specialpower-upsequencingisnotrequired. Thermal
protection circuitry disables the outputs if the chip temperature
exceeds safe operating limits.
The device is supplied in a 24-pin dual in-line plastic (DIP,
package B) with two pairs of batwing leads as heat-sinkable
tabs for enhanced power dissipation capabilities. The LB
package is a 24-lead surface-mount wide SOIC with two pairs
