NJM2574 NJM2574 LOW VOLTAGE VIDEO AMPLIFIER WITH LPF
The NJM2670 is designed to facilitate the control of two-phase stepper motors by providing the necessary drive capability to each phase. Each H-bridge within the IC can independently control the direction and magnitude of current flowing through the motor coils, allowing for precise positioning and speed control. The device operates effectively at voltages up to 60V, making it suitable for a wide range of applications, from small robotics to larger industrial machinery.
The integrated thermal shutdown feature is crucial for protecting the circuit from overheating, which can occur during prolonged operation or under heavy load conditions. This feature automatically disables the output when the junction temperature exceeds a predetermined threshold, thereby preventing damage to the IC and the motor.
The alarm output serves as a diagnostic tool, providing feedback on the operational status of the system. When an abnormal condition is detected, such as excessive current draw or thermal overload, the alarm output activates, signaling the microprocessor to take corrective action. This integration of monitoring enhances the overall reliability of the system, allowing for real-time adjustments and improved performance.
The NJM2670 can be interfaced with various microprocessors, enabling users to implement sophisticated control algorithms for stepper motor operation. The flexibility of the H-bridge configuration allows for both full-step and half-step driving modes, catering to different application requirements. In summary, the NJM2670 is a robust and versatile solution for driving two-phase stepper motors in various electronic applications.The NJM2670 is a general-purpose 60V dual H-bridge drive IC. It consists of a pair of H-bridgesa thermal shut down circuit and its alarm output. The alarm output CAN detect application problems and the system reliability will be significantly improved if monitored by Micro Processor. Thereforeit is suitable for two-phase stepper motor application driven by Microprocessor 🔗 External reference
