Overview
The LB1935FA-AH is a stepper motor driver featuring dual full-bridge outputs designed for precise motion control applications. It operates within a supply voltage range of 2.2 V to 7.5 V and supports a maximum collector current of 0.4 A per channel. The device is housed in a compact MSOP package with dimensions of 3 x 3 x 1.03 mm, suitable for surface-mount assembly. It functions reliably across an operating temperature range from -20 °C to +75 °C.
Feature Summary
- Dual full-bridge output configuration enabling independent control of stepper motor phases
- Compact MSOP surface-mount packaging optimized for space-constrained designs
- Low-voltage operation capability supporting battery-powered or low-power systems
Applications
- Stepper motor control in embedded systems
- Precision motion control modules
- Compact automation devices requiring low-power motor driving
Procurement Notes
Verify the specific suffix AH against official onsemi documentation to confirm exact electrical characteristics and compliance status. Confirm availability status as distribution channels may indicate limited stock or end-of-life conditions. Ensure the ordering part number matches the required package type and thermal specifications for your design.
Selection Notes
Select this component when a dual full-bridge driver is required for small form-factor stepper motors. The 0.4 A current rating suits low-power applications. Verify that the 7.5 V maximum voltage aligns with the motor supply requirements. Consider the MSOP package constraints for PCB layout and thermal management during the design phase.
Part Context
This part belongs to the LB1935 series of motor drivers from onsemi. It is categorized under Motor / Motion / Ignition Controllers & Drivers. The device is specifically engineered for bidirectional control of stepper motors using a simple interface, fitting into the broader portfolio of power management and motion control ICs offered by the manufacturer.
Replacement Considerations
Check for direct pin-to-pin replacements within the LB1935 family. Verify if alternative packages such as TSSOP are available if lead-free or halide-free variants are required. Consult official substitution guides for any changes in thermal performance or current handling capabilities.
