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.
