Procurement Notes
Verify the specific suffix and package variant against official Analog Devices documentation to ensure compatibility with your design requirements. Confirm availability status through authorized distributors as stock levels fluctuate. Ensure proper thermal management solutions are integrated due to power dissipation characteristics inherent to this driver class.
Selection Notes
Select this component when a dedicated bipolar motor driver is required for brushed DC or stepper motors. It is suitable for designs needing integrated high-current outputs without external discrete MOSFETs. Consider the 36V rating and 3.8A capability relative to load requirements. Evaluate thermal performance within the TSSOP-EP package for your enclosure constraints.
Part Context
This part belongs to the Maxim Integrated motor driver portfolio, focusing on integrated solutions for motion control. It simplifies board space by combining gate drive logic with power output stages. The series targets applications requiring reliable motor actuation in compact form factors, serving as a bridge between control logic and high-power motor loads.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement matches the 28-TSSOP-EP footprint and electrical ratings. Verify pinout compatibility before integration to prevent circuit damage.
