Texas Instruments Integrated Circuits (ICs) - Power Management (PMIC) - Motor Drivers, Controllers UC1717L883B

The UC1717L883B is a bipolar constant current motor driver designed for controlling one winding of a bipolar stepper motor. It supports both half-step and full-step operation modes, making it versatile for various applications. The device operates within a wide voltage range of 10-45V and allows for current control from 5 to 1000mA, which can be selected in steps or varied continuously. This motor driver features built-in fast recovery Schottky diodes for efficient commutation and includes thermal overload protection to safeguard against overheating. It is characterized for operation over a military temperature range of -55°C to +125°C, ensuring reliability in extreme conditions. The UC1717L883B is suitable for use with LS-TTL or microprocessor-controlled systems, requiring minimal external components for a complete control and drive unit. Engineers considering this product should note that it is classified as obsolete, which may affect availability and support for new designs.
