Procurement Notes
Verify the specific suffix EL against official Toshiba documentation to confirm packaging format and reel specifications. Ensure the design accommodates the 48-WQFN thermal requirements and strictly adheres to the 4.75V to 5.25V logic supply limits. Confirm component authenticity through authorized distribution channels.
Selection Notes
Select this component when a fully integrated bipolar stepper driver is required within a limited board space. The 48-pin QFN package necessitates careful PCB layout for thermal management. Verify that the system's logic voltage remains within the specified 4.75V to 5.25V range to ensure proper operation.
Part Context
This part belongs to Toshiba's family of stepping motor driver ICs designed for general applications. It utilizes power MOSFET technology to manage high-current loads efficiently. The device is categorized under PMIC motor drivers and controllers, providing a complete solution for driving two-phase bipolar stepper motors without external power transistors.
Replacement Considerations
Consult official Toshiba substitution guides for verified alternatives. Generic cross-references may not match the specific pinout or thermal characteristics of the 48-WQFN package.
