AMT49413KEVSR-J

Motor Drivers, Controllers 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.
