Overview
2993 DUAL H-BRIDGE MOTOR DRIVERS 2993 Cost-effective monolithic drive electronics for bipolar stepper and dc (brush) servo motors to 30 V and 500 mA is very practical with the UDN2993B and UDN2993LB.
These dual full-bridge motion control ICs integrate separate inputs, level shifting for upper power outputs, control logic, integral inductive transient protection, and source (upper) and sink (lower) drivers in an H-bridge configuration.
The single-chip power IC provides improved space utilization and reliability unmatched by discrete component circuitry.
