STK672-543-E集成電路（IC）的電機驅動器控制器規(guī)格書PDF中文資料

STK672-543-E屬于集成電路（IC）的電機驅動器控制器。由安森美半導體公司制造生產的STK672-543-E電機驅動器，控制器產品屬于電機驅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機電執(zhí)行器的電源。所實現的具體功能和特性集根據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。

Overview

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

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.
