The A2919SLBTR is a dual full-bridge PWM motor driver designed for driving bipolar stepper motors or bidirectionally controlling two DC motors. It supports a continuous output current of 750 mA and can sustain output voltages up to 45 V. The device features internal PWM current control, allowing for user-defined output current limits of 0%, 41%, 67%, or 100% of the maximum level, which is set by a reference voltage and sensing resistor. The A2919SLBTR includes internal clamp diodes for protection against inductive transients and has thermal shutdown circuitry to disable outputs if the chip temperature exceeds safe limits. It operates within a temperature range of -20¬8C to 85¬8C, with special order options available for higher temperatures. The product is housed in a 24-pin SOIC package with exposed thermal tabs for improved heat dissipation. It is important to note that this part is classified as "Last Time Buy," indicating that it is obsolete and should not be used for new design applications. Availability is restricted to existing customer applications, and samples are no longer provided.
