A3984SLP-T集成電路（IC）的電機驅(qū)動器控制器規(guī)格書PDF中文資料

A3984SLP-T屬于集成電路（IC）的電機驅(qū)動器控制器。由Allegro MicroSystems制造生產(chǎn)的A3984SLP-T電機驅(qū)動器，控制器產(chǎn)品屬于電機驅(qū)動器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機或相關(guān)機電執(zhí)行器的電源。所實現(xiàn)的具體功能和特性集根據(jù)預期負載和預期應用的特性有很大差異，范圍從用于有刷電機的簡單開環(huán)速度控制到基于步進電機的高級閉環(huán)運動控制。

Description

The A3984 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A3984 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes.

Features and Benefits

?Low RDS(ON) outputs

?Automatic current decay mode detection/selection

?Mixed and Slow current decay modes

?Synchronous rectification for low power dissipation

?Internal UVLO and thermal shutdown circuitry

?Crossover-current protection
