DUAL FULL-BRIDGE  
PWM MOTOR DRIVER  
The UDN2916B, UDN2916EB, and UDN2916LB 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 opti-  
mized 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 UDN2916B 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 UDN2916EB is supplied in a 44-  
lead power PLCC for surface mount applications. The UDN2916LB is  
supplied in a 24-lead surface-mountable SOIC. Their batwing construc-  
tion provides for maximum package power dissipation in the smallest  
possible construction. The UDN2916B, UDN2916EB, and UDN2916LB  
are available for operation from –20°C to 85°C. The UDQ2916B and  
UDQ2916LB are available for operation from –40°C to 105°C. All
