The component is housed in a compact 33-pin QFN package measuring 4mm x 4mm, facilitating integration into space-constrained applications requiring 48V voltage support.
Feature Summary
- Designed specifically for driving single-phase motors
- Output stage supports direct drive of external power MOSFETs at 48V
- Utilizes a compact 4mm x 4mm QFN package
Applications
- Single-phase brushless DC motor drives
- 48V DC rail powered systems
- Battery-powered motor applications
Procurement Notes
Verify the specific suffix (VB) against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure compatibility with the intended 48V motor control architecture. Cross-reference the part number with Nuvoton Technology Corporation Japan documentation for accurate ordering specifications.
Selection Notes
Select this component when a dedicated gate driver for single-phase motors is required within a 48V system. The small QFN footprint makes it suitable for designs where board space is limited. Confirm that the external MOSFET selection aligns with the driver's output capabilities.
Part Context
This device belongs to Nuvoton's portfolio of gate driver integrated circuits. It serves as a pre-driver stage, often paired with external transistors to handle higher current loads. Evaluation kits like KE-KA44370A are available to assist in development for 1.3A peak current applications.
Replacement Considerations
Consult Nuvoton's official substitution guide for verified alternatives. Generic replacements may not match the specific 48V output stage characteristics or the 33-QFN form factor required for existing PCB layouts.
