Overview
The A4919GETTR-T is a three-phase MOSFET gate driver IC manufactured by Allegro MicroSystems. It integrates high-side and low-side drivers in a 28-QFN (5x5 mm) package with an exposed pad. The device operates on a supply voltage range of 5.5V to 50V and supports TTL logic inputs with VIL of 0.8V and VIH of 1.5V. It features six independent drivers with typical rise and fall times of 35ns and 20ns, respectively. The component is designed for surface mount installation and functions within an ambient temperature range of -40°C to +105°C.
Feature Summary
- Integrates six-channel gate driving capability for three-phase brushless DC motor applications
- Supports direct interface with TTL-compatible control logic signals
- Designed for automotive-grade reliability with extended thermal operating range
Applications
- Three-phase BLDC motor control systems
- Automotive fan and pump drive circuits
- Industrial motion control interfaces
Procurement Notes
Verify the specific suffix 'GETR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 28-VFQFN exposed pad thermal design meets the target application's heat dissipation requirements. Ensure compatibility with the intended PCB footprint dimensions and soldering profiles for QFN packages.
Selection Notes
Select this component when a compact, integrated solution for three-phase MOSFET driving is required without external discrete drivers. The 28-QFN package offers a small form factor suitable for space-constrained designs. Verify that the input logic levels align with the microcontroller or controller unit being utilized in the system architecture.
Part Context
This part belongs to the A4919 series of three-phase controllers from Allegro MicroSystems. It serves as a dedicated gate driver stage for power MOSFETs in motor drive topologies. The series is characterized by its integration of high-voltage drivers and protection features within a single semiconductor die.
Replacement Considerations
Cross-reference with other Allegro A4919 variants such as A4919GLPTR-5-T for alternative pinout or packaging options. Verify functional equivalence regarding driver current capabilities and thermal performance before substitution.
