DUAL FULL-BRIDGE  
MOTOR DRIVER  
As an interface between low-level logic and solenoids, dc (brush)  
motors, or stepper motors, the UDN2998W dual full-bridge driver will  
operate inductive loads up to 50 V with continuous output currents of  
up to 2 A per bridge or peak (start-up) currents to 3 A. The control  
inputs are compatible with TTL, DTL, and 5 V CMOS logic. Except  
for a common supply voltage and thermal shutdown, the two drivers in  
each package are completely independent.  
For external PWM control, an Output Enable for each bridge  
circuit is provided and the sink driver emitters are pinned out for  
connection to external current-sensing resistors. The chopper drive  
mode is characterized by low power dissipation levels and maximum  
efficiency. A PHASE input to each bridge determines load-current  
direction.  
Extensive circuit protection is provided on-chip. Both ground-  
clamp and flyback diodes for each bridge are provided. A thermal  
shutdown circuit disables the load drive if chip temperature rating  
(package power dissipation) is exceeded. Internally-generated delays  
provide crossover-current protection.  
Dwg. No. W-106  
The UDN2998W is packaged in a 12-pin single in-line power-tab  
package for high power capabilities. Driving either of the bridges at  
the full 2 A dc rating requires the use of an external heat sink. The tab  
is at ground potential and needs no insulation.
