A3901SEJTR-T集成电路（IC）的电机驱动器控制器规格书PDF中文资料

A3901SEJTR-T属于集成电路（IC）的电机驱动器控制器。由Allegro MicroSystems制造生产的A3901SEJTR-T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 A3901 is a dual full-bridge motor driver, designed for low voltage portable applications involving bipolar stepper or brush dc motors. The outputs have been optimized for low voltage drop, with currents up to ±400 mA (±800 mA with outputs paralleled) and an operating voltage range of 2.5 to 5.5 V.

Features and Benefits

▪Low RDS(on) outputs

▪ Full- and half-stepping capability

▪ Small package

▪ Forward, reverse, and brake modes for dc motors

▪ Sleep mode with zero current drain

▪ PWM control up to 250 kHz

▪ Crossover-current protection

▪ Thermal shutdown (TSD)
