A4933KJPTR-T Description

Short technical summary and product information.

The Allegro Microsystems A4933KJPTR-T is a 3-phase controller designed for use with external N-channel power MOSFETs, specifically for automotive applications. It supports a wide supply voltage range from 5.5V to 50V, enabling operation with battery voltages as low as 7V.

 

This driver provides full control over all six power FETs in a 3-phase bridge, allowing for block commutation or sinusoidal excitation of motors. It includes integrated crossover control and adjustable dead time to protect power FETs from shoot-through. An uncommitted differential amplifier is available for bridge current measurement in low-side applications.

 

The A4933KJPTR-T is supplied in a 48-pin LQFP with an exposed thermal pad, suitable for surface mounting. It is compatible with 3.3V and 5V logic and offers extensive diagnostic outputs for undervoltage, overtemperature, and power bridge faults. The device also features a low-current sleep mode.
