Overview
The A4919GETTR-5-T is a three-phase brushless DC motor controller and gate driver manufactured by Allegro MicroSystems. It integrates high-side and low-side drivers for N-channel MOSFETs in a 28-QFN package. The device operates on a supply voltage range of 5.5V to 50V with an operating temperature range of -40°C to +105°C. It features typical rise and fall times of 35ns and 20ns respectively, supporting TTL logic inputs at 0.8V and 1.5V.
Feature Summary
- Integrates six independent gate drivers configured for three-phase high-side and low-side control.
- Supports direct interface with TTL-compatible logic signals for simplified system integration.
- Designed for robust operation within extended industrial temperature ranges.
Applications
- Brushless DC motor drives
- Fan controllers
- Industrial automation systems
Procurement Notes
Verify the specific suffix '5-T' against official Allegro documentation to confirm pinout and electrical specifications, as standard variants may differ. Ensure compatibility with your PCB footprint for the 28-QFN package. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement plans.
Selection Notes
Select this component when a fully integrated three-phase solution is required without external discrete drivers. The 28-QFN package offers a compact form factor suitable for space-constrained designs. Verify that the input logic levels match your microcontroller outputs and that the supply voltage requirements align with your system power rails.
Part Context
This part belongs to the A4919 series of three-phase controllers from Allegro MicroSystems. The series is designed for cost-effective and efficient BLDC motor applications. The GETTR suffix indicates a tape and reel packaging format suitable for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Allegro MicroSystems technical support or official distributor databases for verified cross-reference information.
