DUAL H-BRIDGE MOTOR DRIVERS UDN2993B
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.

See Graph Operating Temperature Range, TA ................................. -20°C to +85°C Storage Temperature Range, TS ............................... -55°C to +150°C IMPORTANT: Load supply voltage must never be applied without logic supply voltage present. NOTE: Output current rating may be limited by chopping frequency, ambient temperature, airflow, and heat sinking. Under any set of conditions, do not exceed the specified maximum current and a junction temperature of +150°C.
Excepting the power supply connections, the two H-bridges are independent. An ENABLE input is provided for each bridge and permits pulse-width modulation (PWM) through the use of external circuitry. PWM drive techniques provide the benefits of reduced power dissipation, improved motor performance (especially torque), and positively affect system efficiency. Separate PHASE inputs for each bridge determine the direction of current flow in the load. Additionally, each pair of (sink) emitters are terminated to package connections. This allows the use of current-sensing circuitry. Both devices incorporate an intrinsic “dead time” to preclude high crossover (or cross-conduction) currents during changes in direction (phase).
These devices are packaged in plastic DIPs (suffix B) or surfacemountable wide-body SOICs (suffix LB) with copper lead frames for optimum power dissipation without heat sinks. The lead configurations allow automatic insertion, fit standard IC sockets or printed wiring board layouts, and enable easy attachment of a heat sink for maximum power-handling capability. The heat-sink tabs are at ground potential and require no insulation. Dual full-bridge drivers with peak current ratings of ±3 A are supplied as the UDN2998W.
