A4930GETTR-T

Overview

The A4930GETTR-T is a single-phase fan pre-driver designed for pulse-width modulated (PWM) current control of single-phase brushless fans. It operates within a supply voltage range of 8V to 36V and utilizes a 28-QFN package with dimensions of 5x5mm. The device integrates high-side and low-side drivers to minimize external component requirements while providing stable switching characteristics.

Feature Summary

• Optimized for PWM current control in single-phase brushless fan applications
• Integrates high-side and low-side gate drivers to reduce external component count
• Provides stable switching performance with reliable thermal behavior

Applications

• Single-phase brushless fan systems
• Pulse-width modulated current control circuits
• High-power motor control cabinets

Procurement Notes

Verify the specific suffix GETTR-T against official Allegro MicroSystems documentation to confirm tape-and-reel packaging and exact electrical specifications. Ensure compatibility with 8V-36V operating ranges and 28-QFN footprint requirements before integration into design schematics.

Selection Notes

Select this component when designing single-phase BLDC fan drivers requiring integrated pre-driver functionality. It suits applications needing reduced bill-of-materials through internal driver integration. Verify that the 28-QFN thermal pad and 5x5mm form factor fit the target PCB layout constraints.

Part Context

This part belongs to Allegro MicroSystems' portfolio of motor and motion controllers. It serves as a specialized pre-driver solution, distinct from full bridge or multi-phase controllers. The device focuses on simplifying single-phase fan drive designs by combining control logic with power stage driving capabilities.
