DUAL FULL-BRIDGE  
PWM MOTOR DRIVER  
The UDN2917EB 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 modula-  
tion (PWM) control of the output current to 1.5 A.

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. Active-  
low ENABLE inputs control the four drivers in each bridge.

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 tempera-  
ture exceeds safe operating limits.

The UDN2917EB is supplied in a 44-lead power PLCC for surface-mount  
applications. Its batwing construction provides for maximum package power  
dissipation in the smallest possible construction. The UDN2917EB is available  
for operation from -40°C to +85°C. To order, change the prefix from 'UDN' to  
'UDQ'. This device is also available on special order for operation to +125°C.
