A1441集成电路（IC）的电机驱动器控制器规格书PDF中文资料

A1441属于集成电路（IC）的电机驱动器控制器。由Allegro MicroSystems制造生产的A1441电机驱动器，控制器产品属于电机驱动器和控制器电源管理集成电路 (PMIC) 系列，可用于控制或操作从某电源施加到电机或相关机电执行器的电源。所实现的具体功能和特性集根据预期负载和预期应用的特性有很大差异，范围从用于有刷电机的简单开环速度控制到基于步进电机的高级闭环运动控制。

描述 Description

The A1441 is a full-bridge motor driver designed to drive low-voltage bipolar brushless dc motors. Commutation of the motor is achieved by use of a single Hall element sensor to detect the position of an alternating-pole ring magnet. A high density merged Bipolar-CMOS semiconductor process allows the integration of the Hall element on the same IC as the motor control circuitry, providing a single-chip solution for enhanced reliability. All necessary circuitry is incorporated within the device package, eliminating the need for any external support components.

Features and Benefits

▪ Single-chip solution for high reliability

▪ Chopper stabilization technique for precise signal response over operating range

▪ 2.0 to 4.0 V operation

▪ Sleep mode pin allowing external logic signal enable/disable to reduce average power consumption

▪ Restart feature

▪ Small package size
