STK672-543-E屬于集成電路（IC）的電機驅(qū)動器控制器。由安森美半導(dǎo)體制造生產(chǎn)的STK672-543-E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(yù)期負載和預(yù)期應(yīng)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。

Overview

The STK672-543-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control.

特性 Features

? The motor speed can be controlled by the frequency of an external clock signal.

? 2-phase excitation or 1-2 phase excitation is selected according to switching the state of the MODE pin (low or high).

? The phase is maintained even if the excitation mode is switched in the middle of operation.

? The direction of rotation can be changed by applying a high or low signal to the CWB pin used to select the direction of rotation.

? Supports schmitt input for 2.5V high level input.

? Incorporating a current detection resistor (0.11Ω: resistor tolerance ±2), motor current can be set using two external resistors.

? Equipped with an ENABLE pin that, during clock input, allows motor output to be cut-off and resumed later while maintaining the same excitation timing.

Applications

? Office photocopiers, printers, etc.
