The L297 Stepper Motor Controller IC is designed to generate four phase drive signals for two-phase bipolar and four-phase unipolar step motors in microcomputer-controlled applications. It supports half step, normal, and wave drive modes, allowing for flexible motor control. The device features on-chip PWM chopper circuits for switch-mode current regulation, which simplifies the design by reducing the number of external components required. This IC operates with a supply voltage of 10V and can handle a total power dissipation of 1W at an ambient temperature of 70¬8C. It has a wide operating temperature range from -40¬8C to +150¬8C. The L297 requires only clock, direction, and mode input signals, which minimizes the load on the microprocessor. It is available in DIP20 and SO20 packages and can be paired with monolithic bridge drivers like the L298N or L293E, or used with discrete transistors. The device includes several important pins such as SYNC for oscillator output, HOME for initial state indication, and ENABLE for chip activation. The control inputs allow for precise management of motor operation, making it suitable for various applications requiring stepper motor control.
