DUAL H-BRIDGE MOTOR DRIVERS
Cost-effective monolithic drive electronics bipolar stepper (brush) servo motors very practical with UDN2993B UDN2993LB. These dual full-bridge motion control integrate separate inputs, level shifting upper power outputs, control logic, integral inductive transient protection, source (upper) sink (lower) drivers H-bridge configuration. single-chip power provides improved space utilization reliability unmatched discrete component circuitry.

Excepting power supply connections, H-bridges independent. ENABLE input provided each bridge permits pulse-width modulation (PWM) through external circuitry. drive techniques provide benefits reduced power dissipation, improved motor performance (especially torque), positively affect system efficiency. Separate PHASE inputs each bridge determine direction current flow load. Additionally, each pair (sink) emitters terminated package connections. This allows current-sensing circuitry. Both devices incorporate intrinsic "dead time" preclude high crossover cross-conduction) currents during changes direction (phase).
These devices packaged plastic DIPs (suffix surfacemountable wide-body SOICs (suffix with copper lead frames optimum power dissipation without heat sinks. lead configurations allow automatic insertion, standard sockets printed wiring board layouts, enable easy attachment heat sink maximum power-handling capability. heat-sink tabs ground potential require insulation. Dual full-bridge drivers with peak current ratings supplied UDN2998W.
