Overview
The LB1935FA-BH is a stepping motor driver manufactured by onsemi, designed for controlling stepper motors. It operates within a supply voltage range of 2.2 V to 7.5 V and draws a working power current of 60 uA. The device supports a maximum power dissipation of 400 mW and functions reliably across an operating temperature range from -20 C to +75 C. It is housed in a Micro-10 surface-mount package, facilitating compact circuit board integration.
Feature Summary
- Integrated stepping motor driver functionality
- Low quiescent current consumption
- Surface-mount packaging for automated assembly
Applications
- Stepper motor control systems
- Motion control applications
- Automotive ignition controllers
Procurement Notes
Verify the specific suffix BH against official datasheets to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through manufacturer documentation before procurement. Ensure thermal management strategies account for the specified 400 mW power dissipation limit in the final enclosure design.
Selection Notes
Select this component when low power consumption is critical for battery-operated or energy-efficient stepper motor applications. The Micro-10 package is suitable for space-constrained designs requiring surface-mount technology. Verify that the required supply voltage remains within the 2.2 V to 7.5 V operational window for reliable performance.
Part Context
This part belongs to the LB1935FA series of motor drivers from onsemi. It falls under the broader category of PMIC and motion control ICs. The series is designed for efficient stepper motor control with integrated protection features typical of modern automotive and industrial driver ICs.
Replacement Considerations
Check for direct substitutes within the LB1935FA family, such as the LB1935FA-AH, ensuring package compatibility and electrical parameter alignment. Verify functional equivalence with other dual full-bridge stepper drivers if form-factor changes are permissible.
