DUAL FULL-BRIDGE

MOTOR DRIVER

DUAL FULL-BRIDGE

PWM MOTOR DRIVER

The A2919SB and A2919SLB motor drivers are 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).

A2919SB

LOAD

SUPPLY

OUT

SENSE

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%, 41%,

67%, or 100% of the maximum level. A PHASE input to each bridge

determines load current direction.

SENSE

OUT

GROUND

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 A2919SB is supplied in a 24-pin dual in-line plastic batwing

package with a copper lead-frame and heat sinkable tabs for improved

power dissipation capabilities. The A2919SLB is supplied in a 24-lead

surface-mountable SOIC. Their batwing construction provides for

maximum package power dissipation in the smallest possible construc-

tion. The A2919SB/SLB are available for operation from -40°C to

+85°C. To order, change the suffix from 'S–' to 'E–'. These devices

are also available on special order for operation to +125°C. For

applications not requiring quarter-step operation, but desire lower

detent or running current, the similar UDN2916B/EB/LB may be pre-

ferred.
