The SLA2113M simplifies the design of stepper motor control systems. Its PWM constant current control ensures stable and efficient motor operation. The built-in protection diodes protect the IC from voltage spikes generated by the motor windings. The TTL compatible inputs allow for easy interfacing with digital control circuits. The IC also includes thermal shutdown protection to prevent damage from overheating, and overcurrent protection to prevent damage from excessive current draw. These features contribute to the overall reliability and robustness of the motor control system. It comes in a SIP (Single In-line Package).
