Overview
The A4975SLBTR-T is a fully integrated bipolar stepper motor driver manufactured by Allegro Microsystems. It operates with a supply voltage range of 4.5V to 5.5V and supports load voltages from 5V to 50V. The device delivers an output current of 1.5A and features a parallel interface. It is housed in a 16-SOIC package and supports step resolutions of 1, 1/2, 1/4, and 1/8. The junction temperature range spans from -20°C to 150°C.
Feature Summary
- Integrates control logic and power MOSFET stages for simplified design
- Supports multiple microstepping resolutions including full, half, quarter, and eighth steps
- Utilizes a parallel interface for direct connection to microcontrollers
Applications
- General purpose stepper motor control systems
- Industrial automation equipment requiring precise positioning
- Office automation devices such as printers and scanners
Procurement Notes
Verify the specific suffix T indicates tape and reel packaging when sourcing components. Confirm that the 16-SOIC package dimensions align with your PCB footprint requirements. Ensure the 4.5V to 5.5V supply voltage constraint matches your system power architecture before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring a compact solution for bipolar stepper motors. It is suitable where a parallel interface is preferred over SPI or PWM controls. Consider the 1.5A current rating and 50V load voltage capability against your motor specifications to ensure adequate performance margins.
Part Context
This part belongs to the A49xx family of stepper motor drivers from Allegro MicroSystems. It shares architectural similarities with models like the A4973 and A4979 but differs in interface type and pin count. The A4975 specifically targets applications needing a balance between control simplicity and microstepping precision.
Replacement Considerations
The A4975SB-T is a DIP variant of the same core driver. Verify package compatibility if substituting surface mount with through-hole designs. No other direct cross-model replacements are confirmed in available documentation.
