Overview
The AMT49413KEVSR-J is a three-phase brushless DC (BLDC) motor controller and MOSFET driver manufactured by Allegro MicroSystems. It operates with an external N-channel power MOSFET array and supports a supply voltage range of 5.5V to 50V. The device integrates a boost pump for gate drive, internal fixed-frequency PWM current control, and synchronous rectification. It features comprehensive protection mechanisms including shoot-through, undervoltage, overvoltage, and short-circuit detection. The component is housed in a 48-pin QFN package with an exposed thermal pad.
Feature Summary
- Integrates a unique boost pump regulator to provide sufficient gate drive voltage even at low battery voltages.
Applications
- Battery-powered electric tools
- Lawn and garden equipment
- Industrial automation systems
Procurement Notes
Verify the specific suffix 'J' against official datasheets to confirm packaging or material specifications. Ensure compatibility with the required 48-pin QFN footprint and thermal management requirements during integration. Confirm RoHS compliance status through manufacturer documentation prior to final procurement decisions.
Selection Notes
Select this component for applications requiring high-current BLDC motor control within a 50V limit. The integrated current regulation and protection features simplify design complexity. Evaluate the 48-QFN package size against available PCB real estate and ensure adequate heat dissipation strategies are implemented for the exposed pad.
Part Context
This part belongs to the AMT49413 series, designed for cost-effective three-phase motor drive systems. It serves as a pre-driver and controller for external power MOSFETs, targeting consumer and industrial markets where efficient speed and torque control are necessary for battery-operated devices.
