Overview
The MAX22210ATJ+ is a high-performance stepper motor driver featuring two integrated 36V, 3.8A half-bridges in a TQFN-32 package. It includes a built-in 128-microstep indexer controlled via STEP/DIR interface and precise current regulation with non-dissipative internal sensing. The device supports slow, mixed, and adaptive decay modes, offering overcurrent protection (OCP), thermal shutdown (TSD), and under-voltage lockout (UVLO) for robust operation.
Feature Summary
- Integrates a 128-microstep indexer and STEP/DIR interface for smooth motion control
- Features non-dissipative internal current detection to eliminate external sense resistors
- Provides multiple decay modes including slow, mixed, and adaptive options
- Includes comprehensive fault protection such as OCP, TSD, and UVLO
Applications
- Stepper motor control systems
- Motion control applications
- Industrial automation equipment
Procurement Notes
Verify the specific suffix 'ATJ+' against official Analog Devices documentation to confirm the exact temperature grade and packaging configuration. Ensure that the selected variant aligns with your thermal management requirements and PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when designing systems requiring high-efficiency stepper motor driving with integrated microstepping capabilities. Consider the thermal performance limits based on your PCB grounding and ventilation conditions, as the maximum RMS current is thermally limited rather than solely defined by electrical ratings.
Part Context
This part belongs to the MAX22210 series of motor drivers from Analog Devices (formerly Maxim Integrated). It is designed for applications demanding high precision and efficiency in stepper motor control, leveraging advanced internal current sensing and indexing technologies to simplify system design.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Generic cross-references may not match the specific internal architecture or pinout compatibility required for this driver.
