STK672-630C-E屬于集成電路（IC）的電機(jī)驅(qū)動器控制器。由安森美半導(dǎo)體公司制造生產(chǎn)的STK672-630C-E電機(jī)驅(qū)動器，控制器產(chǎn)品屬于電機(jī)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(jī)或相關(guān)機(jī)電執(zhí)行器的電源。所實(shí)現(xiàn)的具體功能和特性集根據(jù)預(yù)期負(fù)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(jī)的簡單開環(huán)速度控制到基于步進(jìn)電機(jī)的高級閉環(huán)運(yùn)動控制。

Overview

The STK672-630C-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control.

特性 Features

? Built-in opened motor pin detection function (output current OFF).

? Built-in overcurrent detection function (output current OFF).

? Built-in overheat detection function (output current OFF).

? If opened motor pin, over-current, or overheat detection function is activated, the FAULT1 signal (active low) is output. The FAULT2 signal is used to output the result of activation of protection circuit detection at 3 levels.

? Built-in power on reset function.

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

? 2 phase or 1-2 phase excitation switching function.

? Using either or both edges of the clock signal switching function.

? Phase is maintained even when the excitation mode is switched.

? Rotational direction switching function.

? Supports schmitt input for 2.5V high level input.

? Incorporating a current detection resistor (0.141Ω: resistor tolerance ±2), motor current can be set using two external resistors.

? The ENABLE pin can be used to cut output current while maintaining the excitation mode.

? With a wide current setting range, power consumption can be reduced during standby.

? No motor sound is generated during hold mode due to external excitation current control.

Applications

? Office photocopiers, printers, etc.
