Overview
The A4919GLPTR-3-T is a three-phase MOSFET driver manufactured by Allegro MicroSystems, designed for brushless DC motor control applications. It integrates an internal voltage regulator to simplify power supply requirements. The device operates within a supply voltage range of 5.5 V to 50 V and supports output currents up to 150 mA per phase. It features a TSSOP-28 package with exposed pad for enhanced thermal performance. The component functions across an extended temperature range from -40°C to +105°C, ensuring reliability in demanding environments.
Feature Summary
- Integrates an internal linear regulator to reduce external component count
- Provides dedicated gate drive outputs for three-phase MOSFET configurations
- Supports sensorless commutation algorithms for BLDC motor control
Applications
- Brushless DC (BLDC) motor drives
- Fan and pump control systems
- Industrial automation equipment
Procurement Notes
Verify the specific suffix '-3-T' against official Allegro documentation to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with your PCB footprint, specifically the TSSOP-28 package dimensions. Confirm that the integrated regulator meets your system's voltage regulation needs without additional external circuitry.
Selection Notes
Select this component when designing compact three-phase motor drivers requiring integrated regulation. It is suitable for applications where space constraints limit external discrete components. Consider the 150 mA output current capability relative to the target MOSFET gate charge requirements. Evaluate the thermal performance of the TSSOP-28 package under expected operating conditions.
Part Context
This part belongs to the A4919 series of three-phase MOSFET drivers from Allegro MicroSystems. The series is engineered for efficient BLDC motor control with minimal external support components. The 'GLPTR' designation indicates the specific package type and tape-and-reel packaging configuration for automated assembly processes.
Replacement Considerations
Consult Allegro MicroSystems official substitution guides for verified alternatives. Generic cross-references may not match the integrated regulator specifications or pinout configuration. Verify functional equivalence before replacing in existing designs.
