Designed for three-phase systems
Worcester, Massachusetts, on July 26, 2011- Allegro announced new car three-phase MOSFET driver IC, designed for common in electric power steering system of BLDC motor, engine fan motors, gearbox actuator and the hydraulic pump design.AllegroA4933Mainly used for high power, high torque and high temperature with the combination of circumstances, need MOSEFT extreme application, in the process of the drive MOSFET driver beforehand can provide large MOSFET gate drives and switch capacity.
A4933 dedicated to three-phase system, especially in the use of motor phase current sinusoidal control is the most commonly used in the system.The rectification method can realize smooth running, lower noise, and the load torque ripple minimum.Main features include: provide a complete integrated charge pump gate drive, coping with the battery voltage (Vbb) as low as 7 V and gate drive battery voltage of 5.5 V, the charge pump (TOCP) allows 100% after full of pulse width modulation (PWM), adjustable dead time can be adjusted by the user, adjustable drain to source monitor (VDSTH), and improve the fault diagnosis, in order to improve the user to decode and the ability to identify fault.
48 l eLQFP A4933KJPTR - T provide small, thermal efficiency is encapsulated with exposed bonding pad.
